[Lectura y Escritura de registros, simultáneamente mediante Modbus RS-485 entre un PLC Unitronics V1040 y Variador Powtran PI500]

Estimated Google translation:

-----------------------------------------

Best regards.

I am starting to use unitronics brand PLCs in version V1040 and I need the reading and writing registers between the drive and the PLC to be simultaneous,

the communication is being done through MODBUS RS-485,

I have the problem that the PLC is always sending the frequency register to write to the inverter,

since the PLC receives a signal from a sensor, making feedback with the inverter,

and for some reason this interferes with the other registers, so I cannot read more registers like drive output voltage, amperage.

I hope I have explained myself as well as possible, and have a prompt response from you.

greetings from Ecuador.

 

[Run NTP server on Unistream PLC]

Hi,

PLCs are not intended to be NTP servers.

You can Google for "local NTP server without internet" and select better fitting for you solution.

[Comms novice can't get anything to work.... (V700)]

You use direct connection PLC to PC,

Why you use Default Gateway  D# 192.168.1.1 - it is from different network.

 

[Comms novice can't get anything to work.... (V700)]

What is an IP address you send ping to?

Is this IP inside or outside of your network?

How you configured PLC OP, Mask, Gateway?

Does your network require MAC address registration on DHCP Server and Domain Controller?

 

[Comms novice can't get anything to work.... (V700)]

Review example from VisiLogic Examples:

C:\Program Files (x86)\Unitronics\Unitronics VisiLogic_C\Examples\Version 900\Project examples\Communications\Ethernet\ V700_Ping_Example.vlp

* It is rfecommended to make Init to all sockets to defaults (see Help).

Only change sockets with different configuration.

Take care that "Ping" button is toggle.

So in your test you have to activate MB 56 to see PING reply.

[Multiple Modbus TCP/IP sessions using the same port]

PLC is right.

There is no support for concurrent connections to one TCP port.

Define more ports as TCP Slave/Server for MODBUS TCP, and more connections will be accepted.

*V700 support 8 sockets, so up to 8 external devices can connect to one V700./

 

[Index Data Table Issue]

This is a Warning that value of this tag cannot be displayed on Ladder (display this tag in Ladder require some unnecessary data processing).

But it is stored as supposed.

You can check result in Data Table.

[Unilogic 1.31.106 Not Opening On Older Win 7 and 10 PCs]

After downloading installation file you have to check file properties and unblock it before you start installation.

There is a Button "Unlock" at right-down side of file properties.

Then installation will be without limitation.

As well, after unlocking file you can use option "Install as Admin".

By the way, this explained in "System Requirements" file, which is in the same section as installation file download.
