Hello everyone. My S7-1500 with CM-PtP-RS422/RS485 HF communication module needs to send two Modbus area data, coils range and holding register range, to the Modbus master. Can it be done by one DB containing both colis and holding registers as words at MB_HOLD_REGISTER in Modbus_Slave block?? I could not find Data_Area_Array[] in Modbus_Slave instance DB as described in Access to data areas in DBs instead of direct access to MODBUS addresses help. ------------------------------------------------------------------------------------------ |
