Hi all, to send a SMS via a GSM modem is no problem. Goto: www.siemens.de/Microset and have a look to the description of Set 5 To receive a SMS and to have Teleservice function with the same GSM-Modem is not so easy. Why? 1. To send/receive SMS messages and have Teleservice function at the same time requires to control the onboard port of the S7-200. For SMS send/receive the port must be switched to "Freeport". But in freeport mode you can not do Teleservice because this requires PPI-Mode. The best way is to use the freeport mode by default. Before you connect with Micro/WIN you have to receive a SMS at the S7-200 and switch the Port to PPI-Mode. Than you can use MicroWIN for Teleservice. 2. Receive a SMS with S7-200 is not easy because of the SMS receive sequence in a GSM modem. There are two different ways to receive a SMS with a GSM modem: A: Receive a SMS and store it on the SIM-Card B. Forward the received SMS directly to the RS232 Port of the GSM modem without storring it on the SIM-Card. A: This requests from the userprogram to connect to the SIM-card, check if a SMS is received, and transmit the last received SMS to the port. Also a handling of the received SMS it self is requested because the number of SMS you can store on the SIM-card is limited and so you have to delete it also. B: You can set the GSM modem to forward the SMS directly to the RS232 interface. This requested to have the onboard interface in Freeport mode. Otherwise you may loose SMS-messages. In any case this is a lot programm code only to handle send/receive SMS-Massages and support also Teleservice. I hope this helps. Regards Helmut |
