Hi,
I got S7-300 and CP (CP 341 -RS422/485)[PLC should be MASTER] and on middle voltage device SEL-787 which should be a slave.
I'm still waiting for SIEMENS equipment to arrive, but slave device (SEL-787) I will not have before commisioning.
My question is how to test my program
Option A:
1. Without any single device Master nor slave
Option B:
2. With Master equipment (S7-300 and CP (CP 341 -RS422/485)->6ES7 341-1CH02-0AE0
Communication processor with connection: RS422/485 (RK512, ASCII, 3964(R), printer, loadable driver)
