DeviceNet I/O Link Units
Section 7-7
Note
When using Expansion Unit/Expansion I/O Unit Error Flags (A436)
in the program, set pin 4 on the DIP switch to ON. If communica-
tions are set to be cleared, the timing for clearing outputs and set-
ting the Error Flags may not agree.
(4)
LED Indicators
Used to indicate CPM1A-DRT21 status, as shown in the following table.
(5)
Expansion I/O Connecting Cable
Connected to the expansion connector of a CP1L CPU Unit or an Expan-
sion Unit or Expansion I/O Unit. The cable is included with the DeviceNet
Unit and cannot be removed.
Note
Do not touch the cables during operation. Static electricity may
cause operating errors.
(6)
Expansion Connector
Used for connecting Expansion Units or Expansion I/O Units.
Handling Unit Errors
If a communications error occurs while the slave is on standby, the appropri-
ate bit in word A436 will turn ON. The appropriate bit is determined by the
order in which the Expansion Units and Expansion I/O Units are connected.
The Unit nearest to the CPU Unit uses A436.00. Use these flags in the pro-
gram when it is necessary to detect errors.
