My first post here so please bear with me.
I am in a bit of a quandry at present as to the best way to communicate with a Contrologix PLC.
We currently run Topserver as a opc server, communicating with a number of Omron and Siemens PLC’s. We are currently upgrading a PLC5 system to a Contrologix and implemeting Ignition as the SCADA.
Due to the communication limitations of the plc (500 bytes per packet from what I recall) from a performance point of view, is it more beneficial to talk to Ignition via Topserver or use the native driver within Ignition?
