Yet another Emco PC Turn 55

[SystemsGuy]

So I've managed to get my new-to-me 1999 Emco PC Turn 55 with six turret tool changer up and running quite successfully. I'd now like to get the tool changer functioning - using the original motor control / optical input board. This is the 6 position changer that Jason and at least one other person have evidently been successful in getting up and running. It has one input - "motor forward", and two outputs - Home and tool strobe. Home is rather evident, it triggers once per rotation, and tool strobe triggers one per tool - so six time per rotation.

I was digging through the code commented " ; File: acorn-turret-v2.src / ; Programmer: Mario Lopes /; Date: 14 June 2018. It looks like this has been hard configed for the Gray4 encoding, and that the incremental code has been disabled.

Was hoping that the original code still existed, but I'm struggling to find it here. Also, side question, how are system parameters set? Specifically "SV_MACHINE_PARAMETER_830".

TIA!

It was done, I don't recall which version of software you have to run to use it.
We are about to start testing soon to make sure the PLC's are compatible with the latest software.
Do you have the 4 bit gray logic on that turret? (4 optical sensors?)

It takes a special PLC program for ATC's and unfortunately once implemented, you can not use the Wizard any more. Further, you have to use the inputs and outputs specified to work with the turret PLC.

Hey Marty - no, unfortunately this is the version before the 4-bit gray logic - it's literally two sensors, one indicating home, the other strobes once every tool.

I'm happy to wander down the road of coding, was just hoping that some of the work had been done. I've already had to give up on the wizard to write code to support my Lenze VFD for the spindle.

When you mention using the specific inputs/outputs, that's based on the plc code, right? As long as I'm comfortable managing the inputs/output code myself there's nothing other than the physical hardware limiting me?

Indeed - some good stuff there.

One question - in that thread "None of the code you are posting is supported yet. That's why it's located in deactivated stages, the one shots and macros are not defined and it is not present in the Wizard.".

For the machine values, like SV_MACHINE_PARAMETER_830 - I can obviously code around it, but that would probably make forward compatibility iffy - is there a way to activate those?
