Hi, I do not use Cinterion BGS2T via RS485, but i try to read some manuals and find - it is not modbus device. RS485 is only variant of communication interface. Then you can find p.14 https://www.activexperts.com/files/manuals/cinterion-bgs2t-at-command-set.pdf and use modem via external RS232 to RS485 convertor (it is not possible to select RS485 in Visilogic modem settings). But i think - better way is to change this modem to Unitronics UCR product.

Hi, you can try to use Project Memory Map. Once I managed to exceed the allowable memory of the PLC. The PLC may not have enough memory for the whole project, but changes in the new firmware (software) versions do not cause errors. In update to 80 Visilogic version. The appearance of the memory map has been updated, improved, and now enables you to drill down into the memory allocation by clicking Analyze, at the bottom of the window Then later version has updated Memory Map also.

In general, I think that experiments with measuring the temperature with a PLC should only check the reference points and determine whether the behavior of the sensor resembles the curve of its calibration. If so, as a result, I create a variable to correct the temperature and can shift it in the right direction - up or down. In most cases, I place a metrologically verified temperature sensor on the machine next to the PLC sensor and adjust the readings according to the operating point. That's enough to make the system work. The main thing is the stability of the readings and the expected results of the behavior of the machine during temperature changes. Only once did I have to deal with temperature control with an accuracy of 0.001C. Three independent temperature stabilization systems of three zones built into each other. Therefore, I understand that PLCs are not designed for this. So it's good that you found the cause of the problem and got a stable result. I think that it would be enough to shift the measurement result by adding or subtracting a certain value. But to make a manual correction for all the characteristics of the sensor for a particular PLC does not make sense because with time and heating of the components, it will still shift.

Hi, It look like some problem in ladder. If you have project - you can find subroutine - by Ldr error code on your pic =0x00003FF0. If this error happend on working system and you do not have project - some external hardware EMI noise can do this fatal error. In this case you must ask the machine manufacturer for help. P.S. As i see some problem with internal battery appear - date and time is not current. If you have project in hand - please replace battery before project load.

I try to read Bug report, it is solved in new Vislogic VisiLogic V9.8.94 Bugs Fixed • Fonts: In some cases, fonts were not shown correctly in VisiLogic. ......... • Socket Init: if this was set to PCOM, Modbus did not work. I think something new Ethernet based is added to Visilogic after 9.8.65.... And now this changes make some trouble in "standard" application.

The same PLC program in different programming languages

Sometimes in communication with non Unitronics Modbus device register address must be one unit less than written in the documentation. That is, to read the 0001 register you need to take 0000 address. Please read this topic Joe Tauser post.

Plese read this topic And find in Help file "Vision700 - Using Ethernet"

Since you replaced the EX-RC1 module, checked the conductors (by replacing), the power supply of the CAN modules, remains the only culprit - the PLC itself. I do not recommend anyone to repair the PLC - but you are probably convinced that the CAN transmitter in PLC is probably faulty. You can hire an electronics specialist to test the internal CAN module on the PLC's internal board. There is a well-known chip 78M05 - linear power converter + 5V and CAN driver 82c250 on the PLC motherboard reverse side. Due to the fact that the system worked for a long time without any problems, I think that the 78M05 chip failed. P.S. However, I recommend - once again check the correctness of the power connection (not reverse polarity) and the correct connection of the СAN bus wires. Sometimes the system stops working after someone else's intervention, which is unknown. And we have to look for a problem in places where there are no mistakes.

Is it +24V and GND wire connected and powered on V1210 and EX-RC1 CAN bus power terminal (5pin green connector)?

I use V1040, V1210 - it have the same resolution. Sometimes i swap this panel with V700. You can convert HMI screens from V1210 to V700 by symply change PLC type in HW configuration. But you must do manual resize and shift for all present grafic in V1210 projet. Please do some test and you see - what elements is lost when you change PLC type. Then you can see how to change all Displays for convertion without any losted item. After change PLC type you can correct resized element position for best design. If in your Visilogic application do not present Ethernet communication and add-on card for Ports - all project can be shift to V700.

As i see in PLC output configuration - you use VFD in machine setup. In some case VFD can generate EMI noise. PLC can do something wrong when machine work on fast speed with high EMI noise level. Correct grounding, shilded motor power wire and grounded -24V wire on power supply can solve many problem with PLC.

Hi, standard LDR sensor working resistance 50-100K. Samba RTD input works with approx 100+- Ohm. Then you must use some external cirquit for convert LDR resistance to 0-10V or 0-20mA signal. Something like https://www.electronicscomp.com/ldr-light-sensor-module-india can be used, but it powered by 5V DC and you can use only half of 0-10V range.

Hi, after OS update process we can find normal updated PLC, not updated (update filed but PLC in working condition), not updated - PLC is not started. Standard update process: https://support.unitronics.com/index.php?/selfhelp/view-article/upgrade-or-downgrade-unistream-panel If PLC do not start: https://support.unitronics.com/index.php?/selfhelp/view-article/rescue-procedure-to-recover-unistream-panels If you have problems with standard update - I recommend changing the USB DOK to another new one from another manufacturer. If the process of updating a new PLC has not taken place - you can change the PLC to a new one under warranty. If your attempts are unsuccessful, and you can't quickly replace the controller - I recommend contacting the manufacturers - they have quality online support. https://support.unitronics.com/index.php? Qualified Unitronics employees can remotely check the upgrade process and fix your problem.

Please post your Visilogic Version. I try to simulate this issue on my 7' Samba.

Please try to Set RTC, Initialize & Reset via "Communication and OS" and Download blank project to PLC. Then load your project. If this option not help, i recommend to open ticket on https://support.unitronics.com/index.php.

Min value is 120 > max value 5. It is strange.

I agree, I may not have fully understood the problem. It just so happened that I usually have one monitor. Although with two (or three) is probably more convenient. Also my favorite ... This is a stable version with predictable behavior.

Please read this topic...

You post some ladder code for V700. But you must post in this topic information about both side of connection (V700 and Raspberry PI4) and for what purpose this connection needed.

I support Ausman's words about the need to provide information. As we can see from this topic, at first I thought that the connection of the wires to the module was wrong, but at the same time I could not find the right diagram in the documentation that would illustrate this. Without the wiring diagram and due to the erroneous table of modes - we have a complete lack of information about this new product.

I see you run TPDO2 on Lexium 32A If possible, write a few words about how you managed to do it. No need to share your code, I think a simple explanation of what and where to write will be enough to solve the problem. This may be useful for forum users in the future.

I do not know exactly how to do it in Lexium 32. But i know that Schneider PLC has some unique sequence for operate with VFD and Servo. You can try to do something like decribed on p.50. See chapter --- An initialization sequence must be written to start the operating mode--- I think for sw on something Schneider servo need to send commant for sw off this option before. Then default ON value is ignored. OFF must be sended before send ON.

One quastion. Is it correct (possible) to change IO module mode on the fly? Maybe some restart or power cycle needed?

Hi, i do not find diagram in manual but i think you must connect 0 Aph Input+ Ch# 0 to signal pulse source, and 1 Aph Input - Ch# 0 to commom 0V (-24Vpower supply).
