MAPWAY Network

4 posts in this topic

Dear all,
We have a machine imported from Finland with a very very unusual system here in Brazil that is the MAPWAY network system.

The automation process works with:
- IBM microcomputer equiped with PC-AT (ISA),
installed the Monitor 77 Supervisor System
also connected with the PC-MAPWAY Board TSX MAP CPC742 version 3.0
wired by 75ohm coaxial cable
connected on MAPWAY connection block TSX MAPACC1 and MAPWAY module TSXMAP1074 version 2.0
installed in the rack with PLC model TSX P87420 version 4.3

There's no memory card on the PLC or program downloaded. Thus, the PLC program come from the PC Monitor 77.

The problem is there's no comunication bettween PLC and PC.
Follow the error messsage on the 77 monitor supervisor system:
Column "TEDBASE" = Negative response from PLC 4:0 nad 1:2:0:0:0 RD45:4
Column "SPOOL" = Hard error on device LPT1

There's not much information on internet and schneider web site.
We already replaced all the hardwares like PLC CPU, MAP WAY modulos from PLC, terminal block, and the PC board.
The lights RX and TX is flashing on the plc module and PC board.
There's an configuration in the PLC CPU that I should confirm/set (it may be lost)?
If you could help us with an information, an thought direction will be great!

Hello,

Monitor 77 software is a SCADA similar to Citect, Intouch or any modern SCADA software. The PLC program (including the configuration of the Mapway card) is in the PLC not in Monitor.  All the 7 series processors had an inboard memory so you can see processor without memory card, that's not abnormal. How are the leds on the PLC ? is it in run mode ?

Mapway was great in the 90's but today Schneider don't use this network anymore so you could consider to retrofit at least this part of the system and change as well Monitor who is completly obsolete today as well.

Thanks!
The actual condition indicates that there's no program because the Run light is off and the MEM light is ON.
You're right! I tried download an program and when I turned it off and turned it On, it lost the program, meaning I need replace the battery.
Just to confirm, there's no way to transfer the plc program from Monitor right?

Morning,

You're right, you can not transfer the plc program from Monitor. You need XTEL and PL7-3 software under OS/2 to do it and maybe the PL7-COMM tool but i'm not sure you really need this one cause it was possible to configure the Mapway card inside the PLC program.

So it seems you have lost the program as the MEM led is on and you're right it's probably because the battery that is welded directly on the processor card is dead. It's a little bit complicated to change it because you have to dismantle the card but the good news is that the battery (3,6 v) is always available. Once you have changed the battery you need to perform a complete transfer (binary program plus IO configuration).
