Sorry its long !! I am recieving text from a GSM modem for text msg Send and receive (SMS) works ok but would be better if I could make use of the start code and end code. This way I could cut down on all the crap that is received when a text arrives. I get this  CMTI: "SM",0 I have it stored into D80 and I have that trigger a TXD that sends AT+CMGRD=0 and that tells the GSM to send the msg (The 0 is the current msg in memory) ------ The problem is that there is Carriage  Return and Line Feeds in the received msg ----      AS below ((AT+CMGRD=0 +CMGRD: "REC UNREAD","+19028991212","","22/10/20,16:57:54-16"  Hello this is the msg  OK)) When the PLC sees the carriage return it stops receiving data. And I have no start code or end code setup. (I am using characters received) The way around this is to set a high  character count in the RXD (More than the actual msg (More than the msg length)   The main issue with that is I get garbage in as the msg gets bigger. Its unreliable. I clear the port after each receive and that helps but still get the odd garbage. (Never get garbage when connected to a terminal prg). Any Ideas???? ps Even the Start Code is unreliable as it will start receiving a few characters late. Rob  

Hi experts :D Can anyone help/try to help  with the following conundrums: a) when changing the Ethernet Operation settings from Binary code to ASCII code, the setting are 'saved' in PLC settings, meaning that ASCII code is read as selected after a restart, but the PLC accepts commands and responds in Binary code. b) when adding a new TCP port, the new port is 'saved' in PLC settings, meaning that read as selected after a restart, but the PLC refuses commands on that port (the "Open" LED on the Q71E71-100 card turns on for the duration of the transmission but no reply is received from the PLC) notes: setting software: GX Works 2 target test software: Custom made Driver for MC protocol. (tested and working with FX and Q series  and with ASCII and Binary code) PLC model Q02 (reset performed by removing the battery for more that 2 hours) ports used for test are: 5500 and 4999 (decimal) found 5002 port opened by default (no open setting required) PLC network module Q71E71-100 (new)   I would upload screenshots of the settings but I get this error: "There was a problem processing the uploaded file. Please contact us for assistance."

Hi, Is there any way in order to monitor both PLC(GXworks2) and HMI(WinCCFlex) using only 1 port from the PLC(FX3U)? I have tried it but I'm not able to communicate the other application(one at a time only).   Thanks!
