D3500.x
Notation
means x-th bit of D3500 register. For example D3500.0 is the
least significant bit in register D3500. Another example D3500.8-15 are eight most
significant bits in register D3500 (high byte).
Base of
Diag Record
(D3500) may be changed to another D or R register via
configuration key REGDIAG.
5. Configuration
5.1 How to
Configuration for CMGSM is located inside PLC Fatek. Range of internal PLC registers
D3900 – D3999 is used. Configuration itself is a string of characters. This string is
created via WinProladder (software from PLC FATEK manufacturer), see following
images. This range of registers cannot be used for any other purposes!

Diagnostic Record
, standard base D3500. Structure
Description
0=no connection to PLC, 1=connection to
PLC OK
0=no SMS in receive queue, 1=at least one
SMS in receive queue
result of command AT+CREG:
0=not registered, not searching
1=registered, home network
2=not registered, searching
3=registration denied
5=registered, roaming
Signal quality in percent (0-100) or 255 if
unknown.
Signal BER (0-7) or 255 if unknown.
CMGSM writes value 0x0001 whenever
diagnostic record is refreshed (cca 6
seconds). This is intended for PLC program
to check if CMGSM is alive. In this case PLC
program will write a 0x0000 into this
register and wait for 0x0001 here.
Version of CMGSM3, in high byte is high
version number, in low byte is low byte is
low version number
For future use
If PLC writes value 0xF3A5 to this register
the CMGSM will make reset of itself.
0x0000 – Idle
0x0001 – Execute
command
DiagAtCmd (written by program in PLC)
0x0003 – Command is about to execute
(written by CMGSM)
0x0000 – Command executed successfully
(written by CMGSM)
0x0004 – Exception while executing the
command (written by CMGSM)
32 bit counter which is incremented
whenever CMGSM updates DiagRegisters
area in PLC. The counter is cleared after
restart of CMGSM. The counter value
indicates in a certain way how long the
CMGSM is running without restart (so
called Uptime).
