Setting Routing Tables Section 7-4
Make sure that bit 12 of the DM word shown below is set at 1 (ON) to allow
you to set and use routing tables.
C200HX/HG/HE
Operating level 0: DM 6400
Operating level 1: DM 6420
CQM1H
DM 6400
DM 6450 through DM 6499 can be used as desired if the Routing Table
Enable Bit is set at 0 to disabled routing tables.
7-4-7 Transferring Routing Tables
Routing tables saved on a Programming Device can be read from memory
and transferred to the PCs on the network. First load and transfer routing
tables to the PC connected to the Programming Device. This enables net-
works to be distinguished even when multiple Communications Units are con-
nected, and it enables routing tables to be transferred to other nodes on the
network.
Once routing tables are transferred to the PC connected to the Programming
Device as well as all nodes on the same network, disconnect the Program-
ming Device, reconnect it to a PC on another network, and repeat the proce-
dure.
CPU Bus Units are reset when routing tables are transferred from a Program-
ming Device to a PC to allow set routing tables to be read. Make sure that
resetting CPU Bus Units will not cause equipment damage or dangerous sys-
tem behavior before transferring tables.
7-4-8 Example Routing Table Settings
This section shows examples of routing table settings.
Example 1 The example below shows local network table settings when multiple CPU
Bus Units are mounted in a single CVM1 or CV-series PC.
