S4C 3.2 Close and Open Commands Not Procedure Reference

I'm trying to get my old s4c ABB to write out some serial data, but I am running into issues implementing the OPEN and CLOSE commands. Similar to Makara's thread here.

They show up under the IPL1 communication section, and my robot has the "Advanced Functions" option, but I can't insert either OPEN or CLOSE into the current program. When I try, the teach pendant just beeps at me, and nothing is inserted.

Also taking the program offline and just typing the commands in results in this thread's title when looking at the routine.

Any idea why I can't use/insert these functions? Is there an additional option I am missing?

Yep, iodev var is declared.

Here is the whole code:

MODULE TORMACHR
VAR iodev Port;


PROC Serial_test()
Close Port;
Open "sio1:",Port;
Write Port,"Test";
Close Port;
ENDPROC


ENDMODULE

Here is the error:

I'm beginning to wonder if I have a corrupt install or something like that. This robot was just a pick and place in its past life, so none of the advanced functions were used.

Here is my SIO.cfg

SIO:CFG_1.0:3:1::
#
COM_PHY_CHANNEL:


-Name "sio1:" -Type "sio"


-Name "sio2:" -Type "sio" -Channel 2

I do see the MoveJSync and MoveLSync commands in the IPL, and oddly enough, the robot will place them into the program with no issues.

Open fails altogether, regardless of what I am opening. Same with Close. Both instructions generate the reference error (40079).

By saying that you mean that you did try to open a file instead of the serial port? Or you tried com1? This looks like it will be a tricky one.

Arguments used with OPEN aren't the issue. The controller acts like the OPEN command itself doesn't exist.

Well the problem just fixed itself. Apparently a second p-start was what was needed. Open and close commands are now working as intended.
