Master slave PLC Delta
Simply Modbus Slave 2. It is more likely to happen when the program is opened and closed within a few seconds. Waiting longer or sending a request before closing may help it quit properly. It may quit by itself after a few minutes on some Windows 7 and Vista systems. Although it's okay on others. Work Arounds: It can be forced to quit by right clicking on the taskbar item and selecting close. Using Alt-F4 to quit the program also works better in some cases.
Simply Modbus Slave 7. It is a significantly larger download and has an install program. It appears to be more stable with the newer Windows versions. Simply Modbus Slave 7. Starting the program Double-click on Simply Modbus Slave 2. You will see the demonstration startup window. The progress bar will take approximately 15 seconds to load the demonstration version. During this time, you can press the ENTER KEY and see After purchasing and receiving a license key by email, enter the key and press OK.
The licensed program - goes immediately to the main Simply Modbus Read window and bypasses the demonstration startup window. The demo version - offers full functionality - requires a program restart to send more than six replies to requests.
The Simply Modbus Slave Window Program Summary: When the program is opened, the circular clock indicator spins to show that the program is running. The program monitors the chosen serial port looking for incoming bytes from a modbus master. All bytes received and sent are displayed in the 'Log'.
A lookup is done to determine if the request has a valid SlaveID, function code, data addresses, valid data if writing and valid error detection bytes CRC or LRC. The request must meet the following 2 conditions before a response is generated and sent: 1 The ID in the request the first byte received must match the entered Slave ID, or 'Respond to all Slave IDs' must be checked.
If the ID does not match, the Slave program will ignore the request since it is intended for a different slave. The request must meet the following additional conditions before a response with data is generated and sent: 3 the request must have a function code that matches enabled data in the tables.
Function code 03 or 04 to read registers with a block of register data set with the same code. Function code 01 or 02 to read coils with a block of coil data set with the same code. If not, an exception code 01 is generated and sent.
More specifically, the request must be for register or coil addresses with a hex values that match the register number minus offset for one of the enabled tables. If not, an exception code 02 is generated and sent. For example, A request for 0003 addresses starting from 0002 will match a block setup with Registers 40001 to 40008 and offset 40001. A request for 0007 addresses starting from 0002 will not match the same block, since it needs registers 40003 through 40009.
Since 40009 does not exist in the block, an exception code 02 would be generated and sent. If not, an exception code 03 is generated and sent. For example, A FC16 request to write 0005 16bit addresses must contain 10 data bytes two per address , otherwise an exception code 03 would be generated and sent. When a response is generated, it is written to the serial port and the Log. On a multi-dropped network eg. RS485 with multiple slaves, this application will also receive responses from other slaves.
All messages received will be monitored and processed to determine if they are valid requests from a modbus master. Setup Details: Controls inputs that can be changed by the user are shown in yellow. Indicators outputs that cannot be changed are shown in blue. Enter the input information in the controls to match the Slave you wish to emulate.
Select RTU or ASCII mode. Select the serial port on your PC that is connected to a modbus master. The 1st byte in the Request and Response strings The unit address of the Slave device to be emulated.
When this box is checked, the program will respond to requests directed to any Slave ID. Other Settings: When checked, the program will send the data high byte first When checked, the program will send the data high word first for 32 bit data types.
When checked, the program will apply a random multiplier to the values found in the tables to a maximum of the '%reading' value entered.
The program will then give slightly different responses when the same request is repeated. Context help is available by pressing Ctrl-H while in the program. Information is displayed about items as the cursor hovers over them. Displays a 'Save As..
Empties the log contents. Uncheck this box to keep the log from scrolling when new data is added. Displays information about the program including the program version. Press the Close box 'X' in the top corner to Exit the program. Data Table Setup Details: Press the button to display and change the register and coil tables. Six data tables can be setup that contain the blocks of data for the slave to respond with.
Each register block is set to respond to either FC03 or FC04 read register requests. Each coil block is set to respond to either FC01 or FC02 read coil requests. All values in one table have the same data type. Selectable as 32bit IEEE Floating Point 32bit Unsigned Integer 0 to 4. Sets the register or coil numbers for the block. Sets the difference between the register number and the hex number used in the commands for each block.
A read-only indicator displaying the register or coil numbers as set above. A read-only indicator displaying the hexadecimal equivalent of register or coil numbers minus the offset. This is where the data values are entered. Press OK to accept the changes entered. Press CANCEL to leave the data unchanged. Save and Restore Configurations Displays a 'Save As..
The data file is saved in csv format comma separated values. The file can be edited with a spreadsheet application and reloaded into the program using RESTORE CFG Displays a 'Open File' dialog box to allow selecting a previously saved settings file to load.
The configuration file is saved in tabbed text format tab separated values and appears like this in notepad... The preset tabs in Notepad cause the cells with long labels to push the other columns over. Sending it to, or opening it from, a spreadsheet program like Excel will use the tabs as column delimiters as shown here...
The data can be saved and edited within a spreadsheet and then loaded into the program with the RESTORE CFG button. Physical Connection: To receive requests from a modbus master before sending a message, the serial port needs to be physically connected to a modbus master device. The simplest connection is RS232C on a single serial cable. DTE masters PC serial ports have DB9 male connectors which transmits on pin3, receives pin2 and grounds on pin5.
A DCE slave will have a DB9 Female connector which will allow the use of a straight through cable. A DTE slave will have a DB9 Male connector and will require the use of a null modem cable.
The RS232 specification states a maximum distance of 50 feet at 20kbaud. Slightly longer connections are possible at slower baud rates depending on cable quality and noise in the area. Modems and radios are used to transmit longer distances. These are typically DCE devices so straight through cables can be used. Some MDS non-spread spectrum radios require RTS Delay to be used so a 4th conductor is needed on pin 4. RS485 converters can be used to extend the distance up to 4000 feet at 100kbaud.
This can be a 4 wire or 2 wire system, depending on the converter. This also allows multi-dropping up to 32 devices on one pair of wires. Program Operation: Once the correct input data is entered, the program operates by itself. When bytes are read on the serial port, they are displayed here. The bytes are then processed to see if a response should be generated.
The first byte of the request is shown in 'ID'. This is the Slave Address that the Master is requesting a response from. This hex value is converted to decimal and compared to the 'Slave ID' entered.
The second byte of the request is shown in 'fc'. This is the Function code indicating which table to read from. This program support function codes 01,02,03,04,05,06,15 0F hex and 16 10 hex. If one of these function codes is found in the request, the 'fc okay' indicator will turn green as shown. The 3rd and 4th bytes of the request are shown in '1st register req'.
This is the register address of first register to read. This number is converted from hex to decimal and shown in 'First Register req'. The program then looks for this register in the data tables showing the function code above. If found, the matching table is displayed in 'found in block', and the 'data found' indicator will turn green as shown.
The 5th and 6th bytes of the request are shown in 'number of regs'. This is the number of registers to read. This hex value is converted to decimal and displayed in ' of Registers'.
The 7th and 8th bytes of the request are shown in 'CRC' or 'LRC' if in ASCII mode. The expected CRC or LRC is calculated from the first 6 bytes and displayed in 'Expected CRC' or 'Expected LRC'.
If the two match, the 'crc ok' indicator will turn green as shown. These are error detection bytes lrc ASCII Mode messages are preceded with a colon and the crc is replaced with an lrc longitudinal redundancy check , carriage return and line feed characters.
If the 'ID match', 'fc okay', 'data found' and ' crc ok' indicators all turn green, a response with data will be generated. The data is read from the matching table and a response is generated and returned. A breakdown of the response is shown in the registers table A breakdown of the response is shown in this table.
A scrollbar will appear for responses with more than 5 values as shown here. The columns show the register number including the offset , its value in hex, the decimal value of the data and this value in hex. The response string is generated from the data and shown in 'Latest Response given'. This is an example of a response with 6 data bytes. The bytes in the above data response are explained here: 0A The Slave ID responding 03 The function code 06 The number of data bytes to follow FF FF 00 00 00 01 The data bytes representing the values in the requested registers.
If the 'ID match' and ' crc ok' indicators both turn green, but the function code found is not supported, a response is generated with exception code '01'. If the 'ID match' and ' crc ok' indicators both turn green, but the data is not found in the table, a response is generated with exception code '02'. If the 'ID match' and ' crc ok' indicators both turn green, and a 'write data' function code 05, 06, 15, or 16 is found followed by valid data, the data is written to the tables and an appropriate response is generated.
If the 'ID match' and ' crc ok' indicators both turn green, and a 'write data' function code 05, 06, 15, or 16 is found followed by invalid or missing data, a response is generated with exception code '03'. Troubleshooting Check the physical connection to make sure the correct conductors are on the correct pins and the correct serial port. Check the serial settings in the master device to make sure they match the settings in the slave.
Make sure the serial port driver file serpdrv is in the same folder as Simply Modbus Slave 2.
