DT02 Tool Touchoff Sensor - SUCCESS

[Arrow]

You also have to have message identified at top of program with other messages, and add it to the plcmsg.txt file

[cbb1962]

I'm guessing that once you modify your local src file and we update to V4.14 we will have to make the same changes again - unless Centroid includes it in the src code?

[cncman172]

cbb1962,
You are correct each time you make changes I would have to add the code again. In fact I was examining the source and noticed it must get changed each time you run the Wizard. Why do I think that is the case? Because if you look at my configuration for input and output assignments they are actually in the acorn_mill_plc.src file. As long as I leave the name exactly the same it would work until the next upgrade, I think.

Arrow,
I notice the plc messages, and in some cases some messages did not seem to be added. Will examine that a little closer before I try the compile. My first attempt at compiling the source outside of running the Wizard.

Looks like the messages are defined as constant definitions. Still reading to get more details in the PLC programming guide. Wow lots of reading. Ha Ha

After reading more in the PLC programming manual and taking feedback from Arrow, here is what I have done in preparations of compiling the PLC program. Keeping my fingers crossed. LOL I was a C programmer for years but much of the context of PLC programming is different.

74 PRESS_DT02_TOUCHOFF_SENSOR_TO_INITIALIZE

[cncman172]

Well no dice. I get a compiler error.

Error Line 1780 Col 5: Invalid Action, Compilation Failed

When I started CNC12 I get two undefined PLC message errors (33) and (39), guessing these are caused because I have added a message to plcmsg.txt and the compile failed so the message is not defined.

The main error appears to be where I put the IF in the Initial stage.

IF Tooltouchofftriggered THEN InfoMsg_W = PRESS_DT02_TOUCHOFF_SENSOR_TO_INITIALIZE,

I think my error is I put this in a series of SET, RST and it needs to happen outside of that set of commands.

Russ

[cncman172]

Fixed compiler error by moving my addition, so now it compiles fine but I get a undefined PLC message 33 when I start CNC12. The parts that I modified to add this test are detailed below. My guess is since I am adding this the IF Tooltouchofftriggered test near the front of the initialstage that the messages are not yet defined, but I am just guessing at this point. The entire reason for trying to add this code in the InitialStage is because it only runs one time.

Comments and Suggestions Welcome. Thanks Gang

There seem to be some inconsistencies in the PLC programming manual. This section of the manual says the PLC message must have three sections
MessageNumber MessageLogNumber Message

If you actually look inside of plcmsg.txt you will find the following; Notice how many of the messages do not have the MessageLogNumber. I did not add the log number, so perhaps that is why I am getting my undefined message. But they have many messages in the file that do not have the Log number either, which is confusing?

plcmsg.txt
The plcmsg.txt file contains a list of all the messages that the PLC can send to CNC11. This
facility is used to notify the user of status changes and fault conditions. The typical messages
should not be overwritten by new custom messages, rather new numbers should be added.
The format for each line of the plcmsg.txt file is as follows.
MessageNumber MessageLogNumber Message
There are three fields separated by one space each that must be setup for a line to be valid
and usable. If the line is not formed correctly, you will not know it until the message is trying to
display. The MessageNumber field is exactly the same number as the Message Number in
the above table. The MessageLogNumber causes the printed message to be put in the
msglog.txt file so that problems can be diagnosed by Tech. Support.

Tom,
Thanks for that document that got me closer. Apparently, they have the messages divided up into the types of messages. 5000 range is Warnings, so i updated the plcmsg.txt with the line below. I recompile the code and no errors or warnings. I start up CNC12 no errors or undefined PLC messages. But no output either. LOL

Initially when I start up CNC12 the DT02 will have input4, tooltouchoff triggered, I have a green LED. If I press the DT02 one time it goes to RED, indicating that nothing is touching the DT02. It is now awake. Maybe I can't have this code in the Initialstage. Still learning all this PLC coding I am getting closer I can feel it.
