I/O mapping for M94/95

[kman1967]

Wondering if there is a document available that lists the I/O mapping for M94/95. I would like to force some inputs on the Ether1616 card in a macro.

M94/1 Output 1
M94/2 Output 2

No.

M94/1 sends request #1 to the PLC program. What physical PLC output it affects, if any, depends entirely on PLC logic.

In the case of Acorn controls, the PLC logic in turn depends on your Wizard output selections.

The outputs on the first Ether1616 board are OUT33 - OUT48.

There are no M94/M95 request numbers that specifically turn, say, OUT33 on or off.

If you do not want to do any of your own PLC programming, then you are limited to what the Acorn wizard provides.

You could assign the name "OUTPUT1" (which is not the same thing as OUT1, the first output on the Acorn board) to OUT33. If you do that, then you could use M94/61 or the provided M61 macro to turn it on, and M95/61 or the provided M81 macro to turn it off.

Regarding Uwe's examples:
M94/1 turns on request #1, which in all standard PLC programs is the M3 run-spindle-forward request.
M94/2 turns on request #2, which in all standard PLC programs is the M4 run-spindle-reverse request.
Whether either of those codes turns an output relay on or off depends on whether and where you have assigned SpindleEnableOut, SpindleDirectionOut, SpindleFwd, or SpindleRev; and also depends on whether the rest of the PLC logic would allow the spindle to be started with an auto mode request.

current M94 assignment of you setup is in the PLC,

Here an example
