Hi Henrique and Crossbow, Sorry for just answer to your post, and first of all i would like to thank you for your answer's. During this time i've been studying a like about Modicon M340 and Unity Pro and i just solved the problem with routine in ST, i'm very familiar with C and Delphi so it's very easy to solve the problem. But thank you anyway. Best regards Joao Manuel

Olá Henrique, Obrigado pela resposta, nos PLC Omron eu utilizado a função KEEP para efectuar a alternancia por ex. entre 2 grupos de bombas... Neste momento estou a começar a programar automatos Schneider e estou um pouco atrapalhado. Obrigado

Hi, it's been a few days since the last post. Thank you Sleepy Wombat, i have read your post! Managed to put the system working (a little bit confused, and not working always ... ) Does anyone hear from a program called "Sms Configurator"? used with CJ1M CPU 21 and Gsm Modem Westermo Gd11 ? If anyone know it, can you drop me a line please, i'm really stuck here , and can't get help from anyone else. Best Regards Joao Manuel

Ok, i know that the Sleepy's sample works fine for sending SMS's from the PLC, but my problem is with RECEIVING SMS's in the PLC !!! That's where i can't find any information or help ... Regards Joao Manuel

Yep ! You are right my misstake. That download from Sleepy Wombat help'd me alot when .( Thank Sleepy Wombat) I'm stuck in another thread with a problem that involves receiving SMS in the PLC and i'm not getting any feedbak, maybe you could give me some help ? Joao Manuel

I Morten, I think you have to send in the last byte of your string the HEX '0D'. Regards Joao

Hi to all again, Back to the PLC's world and continuing the project i'm stuck with this strange problem with the processing of the incoming sms's in the PLC, please tell me if i'm correct ! When receiving a new sms the modem sends to the rs232 port the following string : +CMTI:"SM",1 -> that makes 12 bytes in the A393, now the problem is that i am expecting this 12 bytes in the port but sometimes this message apears with less or more chars like without the "+" sign or with spaces in betwen ... !! Does anyone know wy could this be happening ? Regards Joao Manuel

Hi Harald, Sorry about the delay but i've been away from the office. I have used the cable described in the file that anonymous published here, the port setup is RS232C,8N1. This afternoon i will be working on it so maybe later i will have something to say. Regards Joao Manuel

Ok, finally it's sending sms's fine !!! Now the problem is with the reception in the PLC ... Some how the A392.06 reception flag doesn't apear connected when i send a sms to the GD-01 and only the RD led in the modem blink's ... I'm going crazy with this ... Joao Manuel

Hi anonymous, Thank you for your reply, i'm checking the file right now. Regards Joao

Hi again, Ok i understand, but now i'm using a CJ1M and i need to connect a Westermo GD-01 GSM that only works in RS323c mode, and i need to configure the Comm port in the PLC as RS232C, i will use indeed the TXD and RXD functions, my problem is with the cable pinout that i need to build in order to comunicate with the modem. If anyone can help me Regards Joao Manuel

Hi Harald, thank you for your reply. In the Host Link Port - i have to use RS-232C Mode setup Is this the same ? Joao Manuel

I to all, I have this problem and dont know how to solve it. In a near past i used a CPM2A and a Westermo GD-01 gsm modem i managed to put it wrking well, the only thing was that i used a ready made cable provided by the client and i didn't have to worry about the pinout. Now i have this problem, i have another installation and don't have the cable, i've been digging and i got to this pinout which doesn't work and that is my problem .... Can you please help with this problem ? the pinout that i'm using is : DB9 modem side plc side 2-----------------3 3-----------------2 5-----------------9 7 8 shorted 4 5 shorted Please, can anyone give some help with this ? Best regards Joao Manuel
