close multiple FP writes

[jeguna]

Hi,
I have 5 modules (FP-RLY-420). To control each module, I am using FP write. Can anyone help with the closing operation? I mean how can I combine the FP close of each module.

Thanks

The "FP close" Closes all communication resources in the associated .iak file and frees serial ports for other uses.
So, you need only one Close instruction for all the modules you use.
In ordinary use, put "FP open" in the first step of your program, and "FP close" at the last, and link them "FP refnum" terminals.
