TCT101-4ABC-T questions
Posted: 14/02/2022, 15:36
Hello.
First let me preface my questions with the fact that I am an IT person and not an electrical engineer, so forgive me if I do not provide clear information.
The setup we have is:
a) Encoder - it should be measuring in mm. Sending the pulses to the counter in b)
b) TCT101-4ABC-T set as a counter (with settings: P18 (InC1: 50); P25 (CoM1: time); P26 odU1: 0.1; set1=10) (not 100% sure about the settings at this moment)
c) Wago PLC - this is receiveing signals from the Counter relay output into a DI module on the PLC. From there the data are communicated to a webserver.
I have of course checked the manual but it is too unforgiving to non field people so I have to ask instead.
What I would like to know:
1) Is it possible to count also the output signals on the counter while it also serves the below mentioned use case? I have seen in the manual that it has the possibility of 2 counters (the second is disabled by default). (we also do have spare counters I think)
2) Are the settings correct or is there a better way to set this use case up?
The reason why I want to know is that there is a discrepancy between the electronic data (encoder -> counter -> Wago PLC -> webserver) and a mechanical counter I have had attached so that it directly rolled off the wheel of the encoder.
The encoder measures material consumption of an aluminum foil. The discrepancy is around 5% - 6%. (if mechanical counter = 100%, then encoder = 94-95%)
We are basically getting a signal for each 0.5 meter of consumed material and I would like to compare the amount of signals per hour on the counter with the logs on the webserver.
This was not set by me, it was done by the maintenance team in the factory but they got the setup from another part of the corporation in another country.
I just basically want to double-check or understand why this discrepancy is happening. I understand that it may be because the mechanical counter is just not that precise but I have my doubts.
So I want to rule out other possibilities one after another before I just accept that conclusion.
Also the foil is not supplied with a known distance measurement. It is supplied in weight. And it would be very difficult to do tests outside of the machine as the material is difficult to handle.
Thank you.
