Hi guys, I am newbie for mitsubishi, currently I got a job on converting a mitsubishi A series to schneider quantum PLC. software: Melsoft GX developer language: ladder there are a lots of LEDA, LEDC and LEDR using in the mitsubishi ladder diagram. (No LEDB) Exp: --||-----------------------------------------------------[LEDA IX] | -------------------------------[LEDC D110] | -------------------------------[LEDR] I try to look in the manual (MELSEC A/Q programming manual), the LED function was to display on the CPU front screen, but i can't find any front screen on current CPU. Q: 1) any other function of "LEDA, LEDC, LEDR" beside display on CPU front screen? 2) if so, what is the function and which manual I can refer to? appreciate for the help from you guys!! m(-__-)m Thanks

The LEDA LEDB LEDR is a way of using dedicated instruction in the old A series. The instruction you are looking for in this case is IX. Read the dedicated instcution manual for the A series and look for this function. LEDA instruction active always LEDB instrucion pulsed once LEDC Devices needed for instruction LEDR end os instruction Edited 9 Mar 2011 by Gambit
