Hi Everyone. I need to establish a modbus communication using a CPU 414-3 DP FW1.2 via CP443-1 and a third party device. I tried to use the modbus library in this link modbus_library but this library needs a S7-400 CPU FW 6.0 or later because of the Block Privcy support. Is there anyway to establish a modbus communication using my CPU? (414-3 DP FW1.2) and Simatic Manager 5.1. I appreciate any help. |
