10.7.2.2 Output assembly
The output assembly is the cyclical data from the control to the BCL 558
i
. The following
output assemblies are supported.
Output assembly instance 120
Instance 120, attribute 3
Output assembly, length min. 1 byte
max. 263 bytes
The number of data starting at byte 8 is defined in the control while configuring the BCL 558
i
.
This makes it possible to use the assembly with any length.
It is also possible to specify the length of the assembly with one byte and thereby only use
the control bits. With a length of 2 bytes, the I/O monitoring control bits can be used in addi-
tion to the control bits.
Notice!
The use of the assembly is illustrated with examples at the end of this chapter.
Notice!
Formula for calculating the assembly length:
Length of the assembly = 8 + length of the entry data
For entry data with length
10
, the assembly must be configured with a length of
8 + 10 = 18
.
