23.5.2 MOVCOM
The command can be used with MQx only. The MovComm commands enable cyclical
data exchange between MQx and up to 8 MOVIMOT
®
units via the RS-485 interface
with the MOVILINK profile.
For a detailed description, refer to _MovCommDef (page 227).
The variable is defined by the
MOVCOM variable name;
in the Compiler and has the
following structure.
Variable structure of the process data
The process data is coded according to MOVILINK.
INFORMATION
With MOVIDRIVE
®
B and MOVITRAC
®
B, the timeout monitoring is checked for tele-
grams received within the defined timeout interval.
With MOVIMOT
®
, the timeout monitoring is activated with the first received cyclic
frames (ML_FT... at the sender). Acyclical communication deactivates the timeout
monitoring of MOVIMOT
®
.
Once cyclical communication has been started with the _MovCommOn command,
only the _MoviLink command to address 253 (internal) is possible. When using the
_MoviLink command, other units can no longer be accessed.
BusType (H+0)
Bus type (interface)
ML_BT_S1 = 2 (RS485 to MOVIMOT
®
)
Address (H+1)
Individual address or group address for the MOVIMOT
®
to be addressed
0 ... 99 single addressing
100 ... 199 group addressing
255 broadcast
Format (H+2)
Entry of process data for data transfer
3 = 2 process data words cyclically (for MOVIMOT
®
) = ML_FT_2
5 = 3 process data words cyclically (for MOVIMOT
®
) = ML_FT_3
Pd Pointer (H+3)
Number of the variable H" in which the process data is stored or from which
the data to be written is obtained
.
(The data structure for H" is described in detail below.)
Para Pointer (H+4)
Number of the variable H' in which the parameter data is stored or from
which the data to be written is obtained
.
MOVIMOT
®
does not support this function.
