Select "number of I/O byte checking" function
[OCT (Octal), bytes]
(Applied to item
①
on pages 8·20 to 22)
· Select whether to check or not number of bytes of I/O module used for the remote I/O slave
module. Set selection in parameter address 003750

Set number of I/O bytes
[DCM (decimal), word]
(Applied to item
②
on pages 8·20 to 22)
· Set total number of bytes of installed modules when "yes" is selected (address 003750
(8)
= 45
(H)
).
· If the set number of I/O bytes mismatch with the actual number of bytes of the installed module,
the JW-20RS detects as error (error code 92
(H)
).
· Set between 000 to 128 in decimal notation.
Initial value: 00
(D)
for both upper and lower bytes.
Ex.:
If one ZW-16N1 (16 points/2 bytes) and one ZW-16S1 (16 points/2 bytes) are installed,
(Set 2 bytes + 2 bytes = 4 bytes using the JW-13PG)
