12. FBs CMGSM B1 CMGSM User s Manual 1 Introduction FBs CMGSM and B1 CMGSM CMGSM for short are communication modules for FATEK PLC systems FBs xxMC and B1 xxM CMGSM uses the GSM network to transfer the data CMGSM is based on the quad band GSM module EGS5 Gemalto 850 900 1800 1900 MHz CMGSM is backed up by 1200 mAh Li Ion accumulator CMGSM offer three different ways of communication with connected PLC The first one is monitoring and remote control of PLC via SMS CMGSM reads periodically PLC registers containing a flag to send SMS if the flag is set CMGSM reads destination phone number and string of characters text sends SMS and clears the flag If there is a SMS received by 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 CMGSM e g Connection to PLC failure and only the destination phone number have to be set in PLC registers The second way of communication with PLC via CMGSM is dial up data transfer via GSM network CSD The connection can be only incoming for 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 CMGSM communication over the GSM network is GPRS
