(2) When installing in an I/O bus expansion adapter
Connect an I/O bus expansion adapter, JW-31EA (mounted on a basic rack panel), to a JW-32EA
(installed in an expansion rack panel), or between two JW-32EAs using one of the following cable
assemblies. (Max. 8 racks can be connected).
When an I/O expansion cable is connected, do it correctly as shown in the figure below while being
careful of the IN and OUT connection of the I/O bus expansion adapter. If IN and OUT are inversely
connected, the JW300 will not start operation and become either "I/O table verify error 60
(H)
" or "I/
O table registration error 70(H)" status.
- The total length of cables must be no more than 50 meters.
- Put the each end of the shield lead wire of the I/O expansion cable in between the module fixing
screw and the I/O bus expansion adapter, and then tighten the screws.
