16. Click the download Icon

Note: There are 2 baud rate settings,

a. One is for the Configuration port that goes from the serial port on the PC to the 232 programming

port on the PLC. This is used to upload and download ladder logic programs. They refer to it as the

Communication Settings in the WindLDR software. The default is 9600, 7, even,

b. The other is for the 485 port on the PLC which is speaking Modbus RTU, when you chose Modbus

RTU master for Port 2 the baud rate is automatically set to 9600, 8, even, 1. This is the baud rate

you would set your Modbus software on your PC to in order to communicate to the radios. This can

be changed but you have to make sure you change the baud rate on the Wireless Serial radio

modems (ZP24D-192-RM) to match.

Set up the 2 slave PLC’s

1. The slave PLC’s do not need a ladder logic program written to them for this particular application we are

using. Ladder logic program can be added to allow the slave to do additional features such as reading

and writing to the master PLC.

2. Power up one of the slave PLC’s and connect the configuration cable.

3. In the WINDLDR software click Configure—PLC Selection and choose FC5A-D16R (it should already

be set to this, but it is a good idea to double check.

4. Click OK

5. Click Configure—Function Area Settings and click on Communication tab.

6. Click under Port 2 in the Communication Mode column and select Modbus RTU slave. This window

pops up.

7. Click OK

8. Down load to the PLC
