In this Case i already know that i have to send on RS485 Bus /11920Baud 8 Data Bits 1 Stop Bit Parity: None the following Frame(hex): 80 01 00 05 0B 04 92 00 00 00 06 10 05 80 80 0B F0 40 Answer: 40 01 20 0B 05 04 92
I'm developing SCADA graphics, and was just supplied with an address list from the PLC programmer. After looking over manuals/webinars/forum posts I'm looking to get some verification on whether I got the Modbus addressing correct or not. This is my first experience having to interface with an Unitronics PLC... I'm used to AB or SCADAPacks mostly...
