1: The remote master station includes the multiplexed remote master station and multiplexed remote sub-master station.
2: On a multiplexed remote I/O network, one of 64 remote I/O stations works as a multiplexed remote sub-master station.
3: The optical fiber cable (A-2P-
) differs in interstation distance between the L and H types. Refer to Section 4.8.1 for details.
4: Two slots are occupied.
Set the numeric value resulted from adding 10
H to the I/O No. of the slot where a module mounted as the “Starting I/O No.” of the
“Network parameter”. The first empty 16 points can be set to “0” on the “I/O assignment” tab screen within the “Q Parameter” screen.
Example: Set 10
H as the “Starting I/O No.” when the module is mounted on slot 0.
(Set 0
H as the “Starting I/O No.” when 0 has been set to slot 0 on the “I/O assignment” tab screen.)
