Parameter Setting
WAGO-I/O-SYSTEM 750
I/O Modules
Parameter Value range Meaning
A0 … A7 0 ...255 Word address of the parameter to be read / to be written.
TGL_MS 0, 1 Toggle bit to release new instructions from the
application to the module. If TGL_SM and TGL_MS
have the same status, no new instruction has been
released yet. If the flags have different statuses, a new
instruction has been released and is currently being
processed.
0 Parameter data of A7 ... A0 are read PRM_RW
1 Parameter data is written to A7 ... A0
0 End of parameter transmission MORE_PRM
1 More parameter data to follow
TGL_SM 0, 1 Toggle bit indicating that a parameter sent by the module
has been transferred. If TGL_SM and TGL_MS have
different statuses, the corresponding instruction is
processed by the module. If both flags have the same
status, the instruction for the parameter that was sent or
requested is completed.
0 The transmission of the parameters has been completed
within the stipulated time (parameter address 0). TIMEOUT
1 The maximum time for the transmission of the parameters
between I/O module and application was exceeded.
0 Access to the write or read buffer of the I/O module was
permitted. BUF_OVF
1 Parameters outside of the write or read buffer were
accessed.
0 The parameter/all parameters previously transmitted are
valid. PRM_ERR
1 At least one transmitted parameter was defective. The flag
can either be set after each parameter that is received or
after the transmission of the parameters is completed.
