  1. A1SH CPU PLC

    Hi If the 8 modules on the 1ST rack all require 32 i/o, ie 2 off 32 input modules, 2 off 32 output modules and 4 off 8 channel analogue input modules, (8 X 32= 256) the full 256 i/o available would be used and the modules on the 2ND rack would not work is this correct. I have told my customer he must replace the A1SH cpu for a A2HS cpu with 512 i/o available addressing. Again is this correct. Thanks Gengus
  2. A1SH CPU PLC

    Hi Panic Mode I checked over my customers PLC today, If I am correct the max i/o addressing for the A1SH cpu is 256, This is achieved on 8 slots with 32 i/o each, as the analogue inputs take 32 points the 2nd slot will not work, is this correct. thanks gengus

  4. A1SH CPU PLC

    Thanks for the help. Ive had a look through the PLC code and the highest input address is x101 and y79 for the output. Is it possible to check the actual configuration during monitor mode using GX developer. If so how do you find this function. Thanks Gengus
  5. A1SH CPU PLC

    Hi I am new to Mitsubshi PLC and would like a bit of help with the I/O adressing. A customer has an older A1SH PLC on 2 racks, and would like an extra 16way output module adding to the 3rd slot on the 2nd rack, but with no documentation and no comments in the CPU i am finding it difficult to adress the new inputs. the set up is as follows: RACK No.1 PSU CPU 0-0 32 INPUT CARD 0-1 32 INPUT CARD 0-2 32 OUTPUT CARD 0-3 32 OUTPUT CARD 0-4 8 ANALOGUE INPUTS 0-5 8 ANALOGUE INPUTS 0-6 8 ANALOGUE INPUTS 0-7 8 ANALOGUE INPUTS RACK No.2 1-0 8 ANALOGUE INPUTS 1-2 16 OUTPUT CARD 1-3 16 OUTPUT CARD. What is the lead I/O of this card. Any help would help. Thanks Gengus
