Technical support / Re: Monitoring of Com 1 and Com 3 for Ascii
« on: November 18, 2021, 04:14:09 AM »
Hi Gary.

Thanks for the advice. Your advice has been most useful. I'm using incomm(1) and managed to read 170 characters into dm, converting them into 3 string and send them out using print #3 A$; print# 3 B$; print #3 C$. However, the receiving system at #3 cannot get the correct sent message. It can however, get the correct message if the string is 12 characters long. Any idea why? Port speed mismatch?

Hi Gary. Thanks for the advice. Had it sorted out. However, I have a question. What can I do if I want to receive, modify portion of the string, and  send out a super long string that consists 400 character from Port 1 to Port 3? Can it be done?

Hi. I was playing around with FMD88 and run into a problem. I wanted to use FMD88 to emulate a computer sending out a command "PASS/n" but failed. /n is CR right? So I left it out since CR is automatically sent at the end of the sentence. Correct me if I'm wrong.

Print#1 "PASS"
Outcomm 1, 26

The receiving computer software always prompt that end of line is not received. Any idea why?

Hi. I'm trying to use FMD88 as an Ascii interchange where Ascii command will be coming in from Com 1 and send out to Com 3 or vice versa. Any idea can it be done?

Technical support / Re:Webserver and excel link on startup
« on: June 26, 2018, 02:54:45 AM »
Hi. I'm using win XP system to run only TLServer, ExceLink, Excel and a exe file which is activated by Excel Shell occasionally. Excel 2013 and connected to FMD88 via RS485.

Error 1: com.neva.DdeException ddeError=0x400b - A request for a synchronous poke transaction has timed out
Error 2: com.neva.DdeClientTransactionEvent[source=com.neva.DdeClient@1d10a5c]
Error 3: com.neva.DdeException ddeError=0x4006 - Invalid parameter

Sometimes, I see these errors but the program can still run normally.

Hi. I'm currently doing that but there is a possibility of the windows being accidentally closed. Besides, it will look more professional if both the TL server and Excel link is running in the background instead of being minimized in the bottom tab. Any way to run both in background?

Hi. I'm thinking of deleting the entire program in PLC permanently when a counter is up. Is there any key words that can enable me to do it using Tbasic? Thank you.

« on: June 28, 2015, 08:12:29 PM »
Hi Gary. Thanks for the advice. Do you know if I can hook up anything to FMD88 to detect the line current? Need to detect maximum 1 amp dc current in a wire. If the line current falls below 1 amp, I'll get the PLC to send a notification.

Technical support / Input from other Plc output

Hi. Can the input of fmd88 be connected to the output of another Plc sharing the same power supply? If I connect both together and everything works as normal, does it mean that it should work? Thank you.
