Parameter Sets

For use of the parameter channel, parameter sets are defined and indexed using
parameter addresses (A7 ... A0). Module-specific parameters (parameters 0
through 249) and general system parameters (parameters 250 through 255) are
differentiated.
6.3.4.4

Process of Parameter Transmission

Parameter data is exchanged between the application and 750-644 I/O module via
request/response process. The application initiates an instruction using the toggle
bit (TGL_MS != TGL_SM). The application then queries the communication
control register (R57) of the 750-644 I/O module until the I/O module confirms
execution of the instruction (TGL_SM == TGL_MS).
The possible instructions to the parameterization interface of the 750-644 I/O
module are listed in below:
Manual
Version 2.0.0, valid from FW/HW Version 03/03
Value Description
range
0 ... 255 Word address of the parameter to be read / to be written.
FALSE, Toggle bit to release new instructions from the application to
TRUE the 750-644 I/O 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.
FALSE Parameter data of A7 ... A0 is read.
TRUE Parameter data is written to A7 ... A0.
FALSE End of parameter transmission.
TRUE More parameter data to follow.
FALSE, Toggle bit indicating that a parameter sent by the 750-644 I/O
TRUE module has been transferred. If TGL_SM and TGL_MS have
different statuses, the corresponding instruction is processed
by the 750-644 I/O module. If both flags have the same
status, the instruction for the parameter that was sent or
requested is completed.
FALSE The transmission of the parameters has been completed
within the stipulated time (parameter address 0).
TRUE The maximum time for the transmission of the parameters
between 750-644 I/O module and application was exceeded.
FALSE Access to the write and read buffer of the 750-644 I/O
module were permitted.
TRUE Parameters outside of the write or read buffer were accessed.
FALSE The parameter/all parameters previously transmitted are valid.
TRUE 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.
FALSE Reserved for expansions.
