Comments: This driver does not Support Suconet K but this may not be a bad thing in most situations, where 1 PLC acts as a "Mail Box" & is also the Suconet Master. Here all PLC-PLC Interlocking goes via the Master PLC & not via the SCADA which is a more reliable setup.

PS4 200

The only setup required for this driver is to load a working program into the PLC, the driver does not work if the PLC memory is empty.


The PS 416 has two ports that may be used -

The PRG port requires no setup, runs only at 9600,n,8,1. With either RS232 OR RS485

The SBI/COM port which must be setup for transparent mode, recomended baud settings are 9600,n,8,2 OR 19200,n,8,2. In addition the Sucoma_A function block must be called every program cycle. The speed of the driver is determined by the rate at which Sucoma_A is called so call it more than once in large programs.
