I have been troubleshooting another engineers logic. There is a couple lines that have real world inputs, IE: I00100 and I00101. Each has it own rung, these inputs are POSCON and feed a reset coil each. One line works fine, one does not. I have verify the inputs are transitioning from off to on, but one reset works, and the other does not. The processor is a CPE-100. Is there a problem using real world inputs with the POSCON instruction? The results are very reliable, the same issue happens every cycle, never any variation. I'm just trying to make sense out of it before changing a "standard" logic program, without explanation. I am a hired gun engineer here for a few months. Don't want to make unnecessary waves.

Modbus address register exchange between Melsec-Q series PLC and ME96SSHA-MB Power meter
RV3.0 posted a topic in Mitsubishi
Please assist me with the following; regarding the ME96SSHA-MB Power meter data transition with Melsec-Q series PLC; We acquire to read various values on dedicated Modbus storage address registers at the simultaneous into a Melsec-Q series PLC via Modbus (TCP or RTU) for calculation purposes. Naturally, since the reading of these variables are to provide accurate instantaneous results, it is a requirement that these values are to be read at one scan. However, as can be seen below, there is a gap in address register range – of which, if all of these are scanned simultaneously, yields an exception error when read. This error is only avoided by scanning these data sets separately – which is not ideal for our application – since accuracy in calculations is imperative. -

FX5u to FX5u Ethernet inter-connection (For data transition). (PLC to PLC communication)
RV3.0 posted a topic in Mitsubishi
Good day I require some assistance with the configuration setup (GX Works 3) for FX5u PLC inter-communication (PLC to PLC), over Ethernet (using the built-in Ethernet port). The purpose of the inter-connection is data exchange. (Values stored within the PLC storage registers such as words and bits). Does anyone perhaps support files on this such as a procedure or example? Thanks -
hello everyone I wrote a program that by positive edge of two inputs as Starts button the motor sets and by positive of stop buton rests it , but it doesn´t work . please help me and say why this problem .thanks OB1.pdf
