Basic Features
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 (850/900/1800/1900 MHz). CMGSM is backed up by 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 data connection using TCP/IP protocol. CMGSM opens the connection in TCP client mode. Any SIM card, that can provide internet connection over the GSM network, can be used. CMGSM connects to IP address and port specified in from PLC. It is important to notice, that the connection can be opened in direction from CMGSM to PC (server) only. PC cannot open a connection to CMGSM because CMGSM has no server implemented and usually does not have public IP address. GPRS has special data transfer properties (data grouping, data transfer delay 1 ... 10 seconds), which are not suitable for WinProladder SW. WinProladder must use dial up data transfer (so called CSD) only.
New features
New version of CMGSM B1-CMGSM is suitable for PLC FATEK B1-xxM. CMGSM is newly equipped with one digital input and one digital output.
Highlights
- Three ways of GSM net use – SMS, GPRS, Data Call
- WinProladder remote GSM dial up data transfer connection (CSD)
- One digital input IN and one digital output OUT
- Local Time and Date (NITZ) from GSM network (availability depends on the GSM operator)
- USB port for module monitoring (for service purposes only)
- Li-Ion backup accumulator – min. 2 days of operation
- Lowest level super watchdog function (HW PWR OFF)
- FBs-CMGSM can be used directly with FBs-xxMC (Port 3)
- B1-CMGSM can be used directly with B1-xxM (Port 1)
- SMS functionality is fully under PLC program control
- No PLC program support needed for CSD and GPRS operation
- LEDs for indication of the CMGSM status and data flow signalization
- Unlimited number of logical and analog inputs and outputs can work with one CMGSM (PLC network)
Typical use
- All FATEK FBs control systems that should be monitored or remote controlled via GSM net
- For GSM monitoring and remote control with high number logical or analog inputs/outputs
- For GSM monitoring and remote control if inputs and outputs are spread in large space using PLC network
