Motion command channel
When the global registers are used as command values (com‐
mand values from the higher-level control unit), note that the val‐
ues will be set to "0" if communication fails (as is typical for in‐
puts).
●
Use as non-volatile (permanent) memory for MLD-S, because the con‐
tents are retained in case voltage fails
The global registers A0 to A31 or AL0 can be used for the following applica‐
ters
tions:
●
Setting parameters online for PLC functions or function blocks
●
Communicating with the external control unit via the master communica‐
tion interface
The global text registers "P-0-1387, PLC Global Register AT0" and
ters
"P-0-1388, PLC Global Register AT1" are available as freely usable text pa‐
rameters with a maximum of 255 characters plus closing "0" character.
The global registers (AT0 and AT1) can be used for the following applica‐
tions:
●
Communicating with higher-level control unit or HMI
●
Defining freely definable diagnostic message texts
Parameterization and commissioning information
The display format for the parameters for general purpose in the parameter
channel can be defined with "P-0-1386, PLC display format Global Register".
P-0-1386 is a list parameter with 68 elements and the following assignment:
Element no.
1..16
17
18
19..34
35..66
67..68

P‑0‑1386, PLC display format Global Register
Limits, names and units of the parameters for general purpose can be de‐
fined as desired with the PLC program. This can be done with the following
functions from the "MX_Base" library:
●
MX_fSetParamLimits
●
MX_fSetParamName
●
MX_fSetParamUnit
Brief description
The motion command channel is an internal data channel for transmitting
consistent inputs of ready-made motion function blocks. These ready-made
motion function blocks can be called directly from the PLC program. Internal‐
ly, the motion command channel is mainly used for implementing "motion
control" tasks or for technology functions. The available motion function
blocks conform to PLCopen, i.e., programs created with the motion function
blocks can be transferred to other targets.
