Hi Lambom,
I have read your recent post,
That you using s7-1200 and TIA software for your project,
I have no any experience using this hardware and software.
Present you using this stuff for trial test and gaining the knowledge on SIEMENS product,
It’s good for technical knowledge and also very challenging for beginner.
If your skip the basic knowledge of PLC world
E.g. binary/byte/hex/word/DINT/REAL or another PLC instruction set, it will invite problem to you.
Spend a time to understand the instruction set. refer to user manual
The previous post you trial test with RMC100 with option module probably DIO module slot I guess,
The option module must the right selection with your Actuator.
What are you doing now manipulate the PLC Digital Output whether using IB, IW,QB,QW and move this value to digital output.
The present PROFILE digital output will match with your RMC100/ETC that you had programmed for
selected profile.
This only POSITIVE/FORWARD Actuator movement,
for HOME/RETURN Position RMC100/ETC Controller
Maybe request NEGATIVE/REVERSE Actuator movement command.
How the RMC100/ETC Controller read/interpret negative sign value if you using Digital Output profile?
The digital 8 bit starting from 0 to 7 the last bit 7 will indicate negative sign if you using analog output +/- 10VDC.
This value/data need to transfer to your RMC100/ETC controller.
This is another challenge for you and to install analog module to configure.
