*1 This byte is used for setting the Swap data, Swap parameter, Checking I/O block status,
and Special function block’s error status. See the following table.
*2 These bit settings are different depending upon the connected master module.
a) When connecting the A and Q series (MITSUBISHI) master module, these bits set to
OFF (Intel format).
b) When connecting other master module, please check these points in the master
module’s manual.
*3 This byte number is the first parameter data of first special function block.

Description
b0
*2
Swap data
(Motorola/Intel)
This bit is used for swapping the byte data within the
word data of special function block’s BFMs.
1) When this bit is OFF (0), byte data is Intel format
within the word data. (Not swapped)
2) When this bit is ON (1), byte data is Motorola
format within the word data. (Swapped)
b1
Cyclic status check of I/O
units
This bit is used for checking status of I/O block.
1) When this bit is OFF (0), the status check of the
I/O units/blocks is not performed.
2) When this bit is ON (1), the status check of the I/O
units/blocks is performed in every cycle.
b2
Error check of special
function units/blocks
This bit is used for checking the error status (BFM
#29) of special function blocks.
1) When this bit is OFF (0), error status (BFM #29) in
all connected special function blocks is not
checked.
2) When this bit is ON (1), error status (BFM #29) in
all connected special function blocks is checked in
every cycle.

Swap word parameter for
BFMs
(Motorola/Intel)
This bit is used for swapping byte data within the word
parameter.
1) When this bit is OFF (0), byte data is Intel format
within the word parameter. (Not swapped)
2) When this bit is ON (1), byte data is Motorola
format within the word parameter. (Swapped)
