FieldPoint communication using Delphi

[DelphiDev24]

Need a way to get/set bits on FieldPoint modules using Delphi 5.

DelphiDev24,

The easiest method is to use the FieldPoint OPC server. Once you have configured the channels in MAX and saved the configuration the channels will be available through OPC.

Here is an example that shows how to create a OPC client in Delphi using DataSockets.

Alternatively you can send serial commands to a FP-1000/1001 using Optomux. See the FP 1000/1001 Programmer Reference manual for more information on Optomux:
