Hy guys, Does anyone worked with Twido PLC (TWDLCAA24DRF or TWDLMDA20DTK) and aditional TMI2AMI4LT analog input module? I need help with these problems : I have to measure temperature with 2 rtd pt100 sensors...In order to do this i cannot find information it TMI2AMI4LT analogue input module supply the sensors with the constant current source they need or i need an external constant current for sensors. Also...what will be the difference between a compact module TWDLCAA24DRF or a modular one TWDLMDA20DTK besides input/output count? Wich is better and why? Hope someone with more experience than me can help me with this problems... Thanks in advance! Ionut Capitanu

Hy, I need to settle a communication between Citect and an energy meter(type Algodue UPM304) and i struggled a lot with no results. The energy meter stores its measurements in hex registers like this : $0000 - 2 word - System Voltage [mV] $0002 - Phase 1-2 voltage $0004 - Phase 1-3 voltage $0006 - Phase 2-3 voltage and i need to read from this in Citect over RS-485 and Modbus. I configured the energy meter as an I/O Dev..and variable tags like this : 400001 - System voltage 400003 - Phase 1-2 voltage ..etc.. I receive in kernel an error like this : Uinit 000008 Driver error 00000257 (0x00000101) 16 I tried to look in the Citect Knowledge Base and also in other location for a hint, but nothing useful... Can someone help me ? Thanks in advance!!
