YASKAWA VIPA SPEED7 - FB 320 - ACYC_RW - Acyclic Access to the System SLIO Motion Module

n During the configuration, make sure that the parameters CHANNEL_IN and
CHANNEL_OUT of the FBs are correctly interconnected.
– CHANNEL_IN is to be interconnected to the input data of the Acyclic channel of
the motion module.
– CHANNEL_OUT is to be interconnected to the output data of the Acyclic channel
of the motion module.
Starting from the base address, the start address of the Acyclic channel for the input and
output data can be reached via the following offset:
n 054-1BA00: FM 054 - Stepper: Base address + 26
n 054-1CB00: FM 054 - 2xDC: Base address + 50
n 054-1DA00: FM 054 - Pulse Train RS422: Base address + 26
Example with base address 256:
CHANNEL_IN :=P#I 282.0 BYTE 10 // Base address 256 + 26
CHANNEL_OUT :=P#Q 282.0 BYTE 10 // Base address 256 + 26
Please note that you specify a length of 10byte, although the Acyclic
channel internally uses 8byte!
12.3.2 FB 320 - ACYC_RW - Acyclic access to the System SLIO motion module
With this block you can access the object dictionary of the System SLIO motion modules
by means of your user program. Here the block uses an acyclic communication channel
based on a request/response sequence. This is part of the input/output area of motion
module.
The following System SLIO motion modules are supported:
n 054-1BA00: FM 054 - Stepper
n 054-1CB00: FM 054 - 2xDC
n 054-1DA00: FM 054 - Pulse Train RS422
Due to the FB 321 internally calls the FB 320 and both blocks access the
same database, for each channel (if multi-channel) you can use only one
of these blocks in your user program! Also this block must be called per
cycle only once!
The data exchange with the motion module must be consistent over the
length of the input or output data! It is recommended to control it via the
process image. You can also use SFC 14 and 15 to consistently read and
write the input or output data.
