8. FBs CMGSM User s Manual 1 Introduction FBs CMGSM is the communication module for FATEK PLC systems using GSM network to transfer the data The device is based on the quad band GSM module 850 900 1800 1900 MHz TC 65i JAVA OPEN CODE Cinterion formerly Siemens which is backup by 1800 mAh Li Ion battery With the same HW there are three different ways of operation available The first one is monitoring and remote control of PLC via SMS FBs CMGSM reads periodically PLC registers containing a flag to send SMS if the flag is set FBs CMGSM reads destination phone number and string of characters text sends SMS and clears the flag If there is a SMS received by FBs CMGSM it is written into PLC registers including another flag SMS received to be processed by PLC program At the end the PLC program clears this flag So these operational SMS must be processed by PLC program both on SMS reception and SMS sending Some status and event SMS are predefined in FBs CMGSM e g PLC power OFF and only the destination phone number have to be set in PLC registers The second way of communication with PLC via FBs CMGSM is dial up data transfer via GSM network CSD The connection can be only incoming for FBs CMGSM that may be initiated from a control center for the purpose of remote system analysis and PLC software tuning and modification by WinProladder SW The third way of FBs CMGSM communication over GSM network is GPRS data connection
