Portal V14, S7-1500 1515-2 PN CPU, and two CM PtP RS232 HF's as Modbus RTU Slaves. Where do I find the parameters IB_Start / IB_Count / OB_Start / and OB_Count as referred to in the "S7-1500 CM PtP - Configurations for point to point connections" manual (Rev 09/2016) p129 ??? I need to create different PLC I/O areas for each Slave connection in the I/Q areas (NOT Holding register area) which have the same Modbus addresses from the Master point of view. For example: The IB_Start parameter gives me this functionality but the Static area of the IDB created by the Modbus_Slave Block does not show them? I have tried versions V2.2, V2.3 and V2.4. Many thanks in anticipation of your response. posted as new topic "S7-1500 Modbus RTU Slave Address Offsets" ------------------------------------------------------------------------------------------ |
