CS/CJ-series CPU Units with Unit Ver. 2.0 or CP-series CPU Units
The GCT (Gateway counter) is always 07 hex. The number of network levels that can be accessed
is always a maximum of eight network levels and cannot be set to a maximum of three network
levels.
When CX-Programmer (CX-Net) Ver.5.0 or later is used, the Standard and Expand(7) options in
the Gateway Counter Setting Dialog Box in the Routing Table Setup are both ignored. When
routing tables are transferred to a CS/CJ-series CPU Unit with unit Ver. 2.0 or CP-series CPU Unit,
the GCT (Gateway counter) is always 07 hex, and therefore uses the Expand mode.
•
Pre-Ver. 2.0 CS/CJ-series CPU Units and CVM1/CV-series CPU Units
The GCT (Gateway counter) is always 02 hex. Therefore, access to a maximum of three network
levels away is possible.
When CX-Programmer (CX-Net) Ver.5.0 or later is used, always select the Standard option in the
Gateway Counter Setting Dialog Box during the routing table setup. If Expand(7) is selected, the
routing tables cannot be transferred.
