CP1E host link communication via serial port gives IC error code for Timer SV Read

[IO_Rack 178]

They were supported but not all the functions of the latest firmware version. I was thinking about the CP1L-E series. I would still strongly suggest updating your software to the latest version.

Hi,

    I'm trying to communicate Omron CP1E unit with PC via serial port using hostlink protocol.  I need to read the Timer/Counter SV value and write the timer/counter SV values to the PLC.  I'm able to use other C mode commands (like RC (timer/counter PV read), WC (timer/counter PV write) etc.) but when I give the command for Timer/Counter SV Read 1 which is R#, I get the response as IC (Undefined Command).   How do I write or read the timer SV Values? 

Example command and response :

@00R#TIMH001028*  (TIMH is the high speed timer, 0010 is the timer number and 28 is the FCS)

Response:

@00IC4A*

Is is that CP1E doesn't support these commands? If so what is the equivalent command that I should send inorder to perform this?

Please help.

 

Hi all, i am require to control my PLC from a pc software which i can read and write the DM and contact on CP1E. I need to know the command to send to my CP1E. 
And according to this post. May I know which manual is able to guide me on the instruction as the post like @00R#TIMH001028* . 

I keep searching in the internet but cant get any manual which showing this.

I was referring to the fact that I issued the @00R#TIMH001028*<0D> command when the timer was a TIMX timer.  When I change the timer to TIMHX, it worked just fine.

I also tried @00R#TIM 001028*<0D> (with the space) and I received this response as well:  @00R#1636*<0D>.  When I changed the timer from TIMHX to TIMX, this command then worked:  @00R#TIM 001028*<0D>.

I did not try it with straight TIM and TIMX (BCD) timers. 

To summarize:  I tried both the TIMH and TIM(space) host link commands.  When a the timer existed for that number of the proper type (TIMHX and TIMX respectively), I received a valid response.  When I changed the timer in the PLC to the wrong type (TIMX and TIMHX respectively), I received the 16 error response.  I did not try with the BCD versions of the instructions (TIMH and TIM respectively).

 

Did you see this post by Michael Walsh?

What does your timer look like in ladder?
