Internet PLC Forum

Hi, I want to ask you about Protocol Omron Host Link of Tri-PLC, Tri-PLC  can communicate by Host Link with just old models of Omron, like C20H, C28H C40H using NETCMD$ command. Nowdays Omron name its Host Link Protocol like "C-mode commands" and it is not compatible with Tri-PLC is it not?

I can response the question myself. I was wrong, I could communicate one Tri-PLC with one Omron CP1H Y20dt-d by RS-485 and using the C-command RR by NETCMD$. Tri-PLC are the best!

Best regards,

John

It is possible to use the PWM outputs to control the firing of the SCR in a Welding resistance spot machine?

Hi, I upgraded the trilogi to the last version with the last java version but when I installed again  the Tri-ExcelLink that I had, it doesn´t open It appears on the shortcuts as Tri-ExcelLink 2.0 , I use XP SP 3 , How can I run it?

Hi,

Please, can you help me?

I have one F2424 working with  a RS-485 network with 6 ICPs Analogue inputs and 12 ABBs AC Drives and two LS AC Drives. With the ICPs modules all is ok, but the communication with the ABBs is too slow, about 25 seconds and cause the excecution time too slow. I use modbus RTU with the drives.

I think my problem is the way I did the dCusfu of the Modbus, I have to use for modbus commands for each drive, I mean are 12 x 4 = 48 modbus commands!

Wich is the the best way to arrange this commands? all in one dCusf?,one dCusf for each drive?, separate writemodbus of the readmodbus in different dCusf?

I'm using this now, one Cusf:
