FX to FX2N 2DA program errors

[ledsam]

Hello All I've just had to replace a old PLC (FX) with the new type FX2N with a special function block 2DA. The old problem i have was converted with GX. i had one error being the amount of lines from one PLC to the other (this is Ok) The fault i have is that the Output Analog does not seem to work with the old FX program. The command line i use with the old FX is ----//--------[TO K0 K1 D400 K1]----------- M26 /------------------------[RST M26]----------- The basic function for this is that the Data reg 400 is updated in the machines operation for speed control voltage output. With the new PLC (FX2N) this is a error in the program (error 6708) operation error. Can anyone tell me what i should rewite to correct this fault as the old command line works fine (short and Sweet) D400 is updated with a MOV command from other Data Reg 401 to 404 Sorry just updated error on command line from K0 to K1 (again sorry Gambit) Edited April 25, 2007 by ledsam

----//--------[TO K0 K1 D400 K0]----------- This command line is wrong. The last device (K0) you can use to batch the instruction. for instance if when the last device is K3 D400 is send to BFM 1 D401 is send to BFM 2 D402 is send to BFM 3 So if you aonly want to send D400 to BFM 1 you should enter K1. This is probably you're error. TO K0 K1 D400 K1 Edited April 25, 2007 by Gambit

The FX2n-2DA uses buffer memories 16 & 17 all others are reserved and cannot be used. Maybe this is the problem.
