You must post VFD model # and (or) VFD communication manual. All of VFD must be configured before connect to any communication (network ID, comm speed, start command source and speed command source must be defined). After that you must use PC Modbus software (and USB-RS485 dongle) for test communication and VFD operation. Only after success with this step you can try to set VFD - PLC communication.

All off Unitronics forum user start from the first project. It is OK to make mistakes. Like you, I once tried to build a reversible pulse counter with one sensor. Due to the imperfection of the mechanics and the inaccuracy of the sensor installation, pulses were lost and the calculation was not stable. That is why I asked if you will reverse your engine. P.S. In Visilogic Help Example projects present Function example V120 Step in Range function. It can be used for pulse count in both direction with defined range. Maybe it can be useful for your application

You must have both - quadrature enoder on the shaft (+24 V PNP type with A, B signal) and Shaft encoder x2 or x4 in HW configuration (A,B encoder wire connected to I0,I1 HS input). And Zero sensor for antenna homing. You can save antena position (encoder count) via ladder and do not need for homing every Power ON.

Yo can use Linearization from Math menu Is your antenna rotate CW and CCW? If yes, you must use quadrature encoder in setup for automatic direction evaluation. Otherwise you must use only one direction for counting position.

Some tips: 1) You must start to use UMI via blank project and configure 1 VFD. 2) Configured Umi can be controled via simple UMI command (from UMI menu) and by changing speed and torqe variables defined in configuration. 3) Is it dip sw on RS485 comm card in correct = RS485 + termination? 4) Is it cable from UMI to RS485 card connected properly? P.S. I do not find any UMI inverters on din rail in Visilogic HW config of your project. ADD UMI to project = add some hidden subroutine that is not visible for user. You must try start to use UMI via project from example for configure 1 VFD.

Hi, you must contact to support@unitronics.com i have the same issue and support help to solve problem via remote connection.

I find some bug in rev 001 Q12136_EX-RC1_test_002.vlp

You have two part of communication: Read inputs and send outputs. This two part must be checked separately. Now if no connection in EX-RC1 - outputs is disabled by module program. Quastions: 1) do you see PLC screen direct (on site)? 2) is it possible to go online Visilogic to PLC and try to see operand? 3) is it possible to connect to your PC via Anydesk?

Hi, i try to solve your issue using info from your project. One problem 9.8.65 version of Visilogic used to create prog for EX-RC1 Your config from project. Read from EX-RC1 input status Output status collect Send process to EX-RC1 And finally project for EX-RC1 for test via 9.8.65 Visilogic. Q12136_EX-RC1_test_001.vlp

Sorry, you type: Now i try to generate project for your EX-RC1. What version of Visilogic you use for connect with new EX-RC1?

Is it problem solved?

Try to post prog for 1210 to me via PM. I look on CAN configuration. Foto of used IO setup needed also. Check CAN wire and +24V power for CAN card. Sometimes it is lost and no communication.

If you post program (in PM if it not possible on forum) and foto of used IO setup with EX-RC1 maybe someone can generate new program for EX-RC1. P.S. Is it CAN card on V1210 powered?

Please find example of communication with EX-RC1 in Visilogic Help menu. ......\Unitronics\Unitronics VisiLogic_C....\Examples\Version 900\Project examples\Communications\EX-RC1 You can compare Example V570_CAN Master with your project for 1210 and create project for EX-RC1 from example file. I think you have INN OUT subroutine in V1210. And it similar to example project. Only input and output setup must be configured

Unitronics provide Ethernet card for Samba https://www.unitronicsplc.com/wp-content/uploads/2015/12/V100-17-ET2_S_TECH-SPEC_10-13.pdf You can use USB-to-RS232 converter and stadard Unitronics RS232 programming cable https://support.unitronics.com/index.php?/selfhelp/view-article/communicating-using-rs232-cable-using-visilogic-software

I think it is not correct. sensor do not answer for this request via Modbus software. Better to use message with time stamp 08:47:56 Poll: 01 03 00 00 00 19 84 00 Operation in PLC must be "read holding registers (3)" Daniel_EWW post good idea to use Array, but topic starter must play with Type of elements and Length of this Array for correct reading from sensor.

You test it via Info mode? You can check soket configuration in PLC via Info mode. Pleas post foto of this configuration

You must know - in NEW PLC downloaded DEMO project. In this project PLC name = Unitronics. After first download another project you reset "Unitronics" PLC name to default PLC name (if new PLC name do not set via your project). Please read about Unitronics Info mode. Tap on screen 5 sec - 1111 password. Then in software section you find default PLC name (some numbers). Use this PLC name for set Ethernet conection via Visilogic.

Hi, download blank project and try Init & Reset via visilogic communication menu. Some tips: 1) Please post V120 program; 2) Please change -| |- contact to -|P|- to use the function Load HMI Display. 3) In posted program present many warning about ladder - V120 and V130 is from different series. Some net from V120 maybe do not work in V130. Something like changed to solve warning problems; 4) Please read this Help topic, some net from V120 program deleted if program converted to V130

Hi , you can use vector copy for solve your problem Joe Tauser post this solution I use it for one of my project P.S. You need V230 on table for simulate program via Visilogic

https://support.unitronics.com/index.php?/selfhelp/view-article/how-many-communication-sessions-can-i-open-at-the-same-time-using-ethernet Please read Visilogic Help about how to configure 4 socket for different connection

Why did you change the processor? Lightning struck? Controllers of the Samba or Vision series cannot be destroyed by software. Even if the screen is dark and the PLC does not start, there is a recovery procedure from the brick state. If the PLC is new and has problems, then there is a manufacturer's warranty. I don't know how to flash the loader to a new processor. This is probably copyrighted by Unitronics. If the PLC does not start and it has normal processor voltages, you should try the information on this topic. https://forum.unitronics.com/topic/6069-vision-bricked-issues-and-how-to-resolve-originally-was-v570-57-t20b-j-bricked/

Some idea from Visilogic world can be useful for Unilogic problem

Remove the protective film from the screen. The touch sensor seems to be triggered by dirt. If there is no result, the touch screen of the PLC is damaged. P.S. Sometimes, during installation in the door, the fasteners of the PLC are tightened too much and this causes deformation of the touch sensor. You can try to loosen the PLC mounting a little.

You can use "Find Operand" option from Visilogic Menu for find any location where MI697 is used in project. Click on Find list you can navigate in ladder and HMI to find possible owerwrite with dedband value. In HMI section of project you can find numeric variable and click on it. Please check value in MIN MAX keypad entry position
