</ETHERNETKRL>not sure what you have in mind... and you did not define what those are so... i just made them integers...
this is easiest to test with $OV_JOG and $OV_PRO because you can see and adjust values any time
and they are defined all the time. for other things some conditioning may be needed...
RET=EKI_SetInt("myEkiConfig", "KRC/Speed", $VEL_ACT*1000) ; 0-2000 mm/sec
RET=EKI_SetInt("myEkiConfig", "KRC/TcpSpeed", $VEL.CP*1000) ; 0-2000 mm/sec
RET=EKI_SetInt("myEkiConfig", "KRC/OV_PRO_Act", $OV_PRO) ; 0-100 %
RET=EKI_SetInt("myEkiConfig", "KRC/OV_Jog_Act", $OV_JOG) ; 0-100 %or if you want to make variables Speed, TcpSpeed a REAL type:
RET=EKI_SetReal("myEkiConfig", "KRC/Speed", $VEL_ACT) ; 0-2.0 m/sec
RET=EKI_SetReal("myEkiConfig", "KRC/TcpSpeed", $VEL.CP) ; 0-2.0 m/sec
RET=EKI_SetInt("myEkiConfig", "KRC/OV_PRO_Act", $OV_PRO) ; 0-100 %
RET=EKI_SetInt("myEkiConfig", "KRC/OV_Jog_Act", $OV_JOG) ; 0-100 %again, this is just an example. to find which variables you want to use, refer to system variable manual...
btw. i would never insert those lines into SPS like that....
i tend to keep all my code in SRC+DAT module. this also allows me to control scope of variables.
for case like this i would simply use an Expert type module. run it as a regular program until debugging is done and it is confirmed that everything works as expected.
then i would just add single line in SPS to call my SRC...
Do you also have PLC in your system? I would say that, instead to make pretty complicated system. You can also make it via I/O interface:
in sps program:
IF($MODE_OP==#EX) and ($PRO_ACT) and (SpeedRequestHMI) THEN
$OV_PRO = SpeedFromHMI (group input or analog input value)
ENDIF
If you are only sending, you van do that indefinitely. Send buffer is populated by writing elements as shown earlier. Send buffer is cleared when message is sent.
same goes for receiving. buffer is cleared by reading. but rate at which messages are received is obviously not something you can control and for that there are commands to check how many messages are queued and optionally clear them. this is covered in the manual.
also check messages and logs. EKI will tell you if something is unexpected.
