Limit switch configuration in beckhoff IPC
genn posted a topic in Other PLCsHi, In our machine, we want the homing of linear axis to be - moving to reverse limit. In order to achieve that we connected positive limit to Enable_positive input, negative limit to Enable_negative input of MC_Power function block. We used MC_Home function block and assigned the negative limit to bCalibrationCam of home FB. Things were working correctly. But one thing we noticed is if the axis is in synchronous operation mode(axis following another master axis), even the limit is engaged axis is not stopping. During discrete movement this was stopping. Is there any other way to configure limit switch in twincat3.
PEERPSI posted a topic in CX-ProgrammerLooking to set a limit in my logic that returns a bit if my process value falls between the lower and upper limit values. Looking at LMT(680) but it does not appear that it switches a bit just passes the value through. Any ideas?
Kinetix 5700 Inverter Fault
Cordy posted a topic in Allen Bradley / Rockwell AutomationHello, Have this error come up constantly and can't be reset. Motor hasn't tried to drive at all. Second motor showing same problem. This is a new configuration on new machine. Other inverters configured without any problems. Anyone seen this before or any ideas what could be the issue.
mr_electrician posted a topic in CX-ProgrammerHi group! I am struggling to figure out what I am doing with the Limit instruction (ZCP 088). I want to turn on a permissive if the compared word is between 1 and 12. Rockwell makes this so much easier!!! It looks like my "=" instruction is not correct but this is how they show it in the manual???????
Limiting on-line connections to a S7-1500 PLC
ErikSN posted a topic in SiemensHi, I was wondering if there is a way to limit the number of allowed on-line connections at a time to a PLC? Like can you somehow set in the PLC parameters that only 1 'connection' can be on-line in the device at a time? Thanks Edit: I'm referring to connections from the TIA portal - not HMI / ethernet connections and so forth
Lexium 32A hardware limit status
genn posted a topic in Modicon / Telemecanique / Schneider ElectricHi, Iam new to schneider electric PLC drive programming and also to canOpen communication. I have an LMC058 PLC and there are three Lexium 32A drives connected via canOpen which inturn controls three servomotors. My question is how to find/ read hardware limit status of the axis in which limit is connected to a digital input pin of the drive. Even though the axis is properly working by configuring the digital input pins we are unable to get the digital input status of the drive. In the drive manual its given that the digital input status can be read from canOpen address 3008:F(hex) we dont know how to read the status during run time in the program . Can any one advise me how to read that address. I tried SDO_read function but its giving me error(canOpen network id Unknown). Thanks in advance.
Changing Online Edit Step Number Limit
pmcmahill posted a topic in MitsubishiLong ago i remember finding a way to change the online step number limit, which is defaulted to 500. But it was probably 15 years ago, and i have forgotten how i did it. Has anyone else found a way to change this?
