Hi. I have a PLC V350 in my application. This PLC is input PNP 24V. The application have end travel sensors but they don't work using other power supply. Why they work only with power supply from PLC? Is related with power from source? Please, sorry for my english and topic in inappropriate place. -
So I ordered a V350-J-R34 controller to input a couple analog signals from a couple pressure transducers. I'm reading the installation guide, and I don't know if I'm just reading it wrong, or legitimately confused here. It says this controller has 2 analog inputs, and that terminals 14 and 15 may be used as the analog inputs. However, when I scroll down to the analog input wiring diagram, it shows the positive end of the signal wires landing on terminal 4. HUH?!?!?! Can someone shed some light on this? It's making me feel stupider by the minute. image hosting free upload image online -
Hello, i have a JZ20-J-T40 and four 4-20mA pressure sensor´s. I need connect for two 4-20mA sensor´s for 0-10V analog input´s. How it could be done . Can i use 500ohm resistore? Sorry for my bad english.

Hi everybody. I need some help because I have an issue, trying to use a Beckhoff BK5120 | CANopen Bus Coupler with a V1210 PLC https://www.beckhoff.com/BK5110/ with the next configuration 4 KL1114 DIGITAL INPUT (4 SINKING) 2 KL1408 DIGITAL INPUT (8 SINKING) 1 KL2134 DIGITAL OUTPUT (4 SOURCING) 2 KL2408 DIGITAL OUTPUT (8 SOURCING) 1 KL3061 ANALOG (0-10V) INPUT https://download.beckhoff.com/download/Document/Catalog/Main_Catalog/english/separate-pages/Bus_Terminal/KL3061.pdf The issue that I have is that I've never used a Beckhoff KL3061 ANALOG (0-10V) INPUT and I don't know how to set up the Unitronics V1210 PLC CANopen configuration in the VisiLogic Software. Also, I'd like to know which function can I use to read the analog input. Does anybody did that before? I'll appreciate your help. Thank you. -
Hi and Happy New 2018 all! Maybe this will sound like a dumb question, I am beginner in programming in VisiLogic, so is there any way to compare current value received from an analog input with a previous value received from the same input. I have tried to use the 'Store Direct' with MI0(analog input operand) value to be stored in MI1 and tried compare MI0(A) with MI1(B), but it always gives me the same value. How to memorize previous value and be compared with the current? How to make MI1 hold the previous value, MI0 to hold the current, and untile they are compared MI1 is not overwritten by the current value? Thank you in advance. -
Hello everybody, Im wondering if you could help me. Im currently doing a project using the V570 and need some help. What im trying to do is setup a login screen were you would have to scan a barcode made specifically for an operator to allow said operator to acess the work screen. My own idea on how to do this would be to save the barcode into the PLCs memory and then use a Comparison function block so when the barcode scans a different barcode, it won't register it but if it scans the same barcode, it will operate and proceed to the next screen. So i suppose what im asking is, is there a way to store a particular barcode into the system and use it as an input? Is the soultion i've discribed above suitable as a login system? I am familer enough ladder logic and fuction blocks but i'm a total novice working with unitronics, Visilogics and barcode scanners systems, so any help would be amazing. Thanks!, Dan P.S. the barcode scanner i'm using is a Metrologic 7120 Orbit barcode scanner incase that has any revelance, Thanks for reading! -
Hello everyone, I'm new on this forum. Yes I made many searches and found nothing. I have a project with V350-35-TA24 and I have to remove all the direct references to I/Os and replace them with MBs, so that I can do the I/O mapping. Do you have any suggestions? Thank you.

Hi, I am very new to the Vision PLC+HMI System. I wish to know the process of interfacing a gear motor with the V530. I need to count the rotations of the motor. -
I'm a new user of Ladder Logic and M91 PLC's. I'm trying to debug a program I have uploaded off of an old PLC. I understand that in U90 there is no way to force input/output states. Considering this how can you check that your logic is correct? E.g. how can I check that a certain combination of inputs will cause a change of state or particular output? [i don't consider a red flow of logic sufficient, especially as I can only see it for the power on state.] Thanks
