Hi Hanna,
IO-PT4 is a predecessor of IO-PT400 (newest one). Both designed to work with PT100.
To work with PT1000, you should use IO-PT4K. This module designed to work with PT1000.
Hi! I'm sorry I was so clumsy. Thanks for all your help. //Hanna

Hi Hanna,
PT-4x module name used in Hardware Configuration. What module do you use? IO-PT400 or IO-PT4K?
PT1000 sensor should be used with IO-PT4K, and PT100 sensor should be used with IO-PT400.
If you use PT1000 sensor with an IO-PT400 - it will be a reason of wrong reading.
Hi! In the module, it is written only IO-PT4. This module, I think we used many years ago with PT1000 sensors? The SN numbers are:91D00535

Hanna,
It will be better if you describe in more details connection between modules.
When you use IO-PT4K, you should use either EX-A1 or EX-A2X Expansion Adapter with a proper cable between it and OPLC.
Cables are different. Cable for EX-A1 has Gray connectors. Cable for EX-A2X has Yellow connectors. Connector with a Groung wire should be connected to OPLC.
IO-PT4K module should be connected to Expansion Adapter with a cmall flat cable.
EX-A1 or EX-A2X Expansion Adapter should pe powered from Power Suply.
Please tell if everything i wrote is implemented.
Hello! The cables name between oplc and expansions adapter EX-A1 are EX1-CA100 (Gray connectors). The side with ground wire (yellow/gren) is connected to oplc.
The EX-A1 has power suply 24VDC. The run lamp on the EX-A1 indicates green and the four channels lamp indicates red (out of range). what more can I test?

Hi Hanna,
There are two I/O Expansion modules,I/O Expansion module IO-PT400 for PT100, and I/O Expansion module IO-PT4K for PT1000.
In VisiLogic Hardware Configuration there is a common I/O Expansion module IO-PT4X.
VisiLogic know to detect which modul is in use.
So when you use PT1000, you should use I/O Expansion module IO-PT4K .
See attached picture, where I measure a temperature of hot water.
Hello again! I do not think my file was with at my answer, try again! Think I have the right user configurable. Check my file! Do not understand why it should not work?

Thanks for your answer! I dont understand how to choose PT4K. Here you have may hardware configration. Is then wrong?

Hello! I have a application whit plc vision 350-35-R2 and expansions module PT4X. I have the latest visilogic program (9.3). The problem is that all my four PT1000 sensor give me value 1000. The temp sensor is two wire connection and i have connect them to (+v) and (-V) on the PT4X. I have also connect (+V) whit (+I) and (-V) whit (-I). All four temp sensors have right resistance (1050-1100ohm). In the hardware configuration i have type PT1000 (385), mode C, adress MI2 - MI5. What can the problem be?
Communicate to plc over 3G mobile network
in Remote Operator
Posted
Hello! Is it possible to communicate over Ethernet with a Vision 350 over the 3G mobile network? I would like to use the remote operator to remotely connect me with this plc. Had planned to connect the PLC to a Dovado 3GN router and a 3G modem Huawei E1820. Is it possible to use dynamic DNS for this or do I have a static IP address?
