Locating and Correcting Cable Disconnections
Sample Program for CS-series PLCs
Sample Program for CV-series PLCs
• As long as the Network Disconnection Flag (CIO 152315 for unit number
0) is ON, the "node address of the disconnected node" in bits 8 to 13 is
stored in D00000 and the "node address of the disconnected node" in bits
0 to 5 is stored in D00001.
• The contents of D00000 are shifted 8 bits to the right to convert the node
address to a proper hexadecimal value.
• The hexadecimal node addresses stored in D00000 and D00001 are con-
verted to BCD.
Note When using the sample program as written above, be sure that the bits and
words in the sample program are not already being used by the program or
other Special Units.
Always ON Flag
• As long as the Network Disconnection Flag (CIO 152315 for unit number
0) is ON, the "node address of the disconnected node" in bits 8 to 13 is
Always ON Flag
