Need programming manual for MicroGem

Greetings, All

I'm looking for a manual for a MicroGem Controller on a GEC Industrial Controls Ltd. Kidsgrove England PLC.
I have a copy of the hand written code, but without a manual I don't know what some of the ladder logic is doing.
We have translated most of the logic, but can only guess at the other logic with out a manual.
Contacting GEC Industrial Controls Ltd has been a wast of time.

Thanks, in advance

I used to work with these little beauties!

Hand written code was the only way of saving a copy of the program which was entered one instructtion at a time with a hand neld programmer.

Can you scan your copy of the logic and post as a pdf?

Alas, I have long since chucked out my manuals but you never know, my memory might be jogged.

Here is a pdf of the code

The pdf was too big to upload on this great web forum.
But you can get it from mailbigfile.com use the following link. http://mbf.me/K5u8
My questions are the following:
Rung 2: What makes a W coil different from a G coil?
Rung 3: What would W37 do?
Rung 20: What would W00 do?
Rung 21: W00 starts a break command <B> does the code inside a <B> to the <EOB> stay ON if enabled or does all the code inside the break turn off?
Rung 26: Why would they use W01, W02, W04 & W08 instead of G01, G02, G04 & G08?

As you can see I just need a better idea of the W coils do.
I have got all the code working with a replacment PLC but the code with W coils is still in question.

Thanks in advance

Try contacting the people at www.gem80.com

microgem

Came across this thread searching for information myself about the microgem 60

I am not a user, but do have some info which may help.
The W relays are internal relays battery maintained
The G relays are internal relays which are non-retentive, and are cleared to zero on power-up
Can't help on w37 or w00

G38 is set on powerup if the W table is corrupted say with flat battery G39 is set if battery is low

Hope that helps

Not sure if you still need

Hi, I stumbled across this post while looking for a manual myself then realised that I have an original manual After a bit of digging in the workshop, I now have said manual if you want a copy, let me know. I realise that its been a while since the originl post but you never know

Yea that was four years ago, the PLC was replaced so the manual is not needed now.
But thanks for the offer.
