4.7.1 SERIAL COMMUNICATION MODULE LED OPERATION

When the Flex M system is supplying power to the Serial Communication module, there is an LED that

indicates the power and communication status of the Serial Communication module.

Figure 26. Serial Communications Module LED Placement

 OK LED

o Solid indicates module communication with system is good

o 3 Blinks indicates read/write error to attached CPU module

Additionally, there are 8 LEDs labeled 1 through 8 on the Serial Communication module.

 When LED number 1 is steady, this indicates an internal CAN bus initialization error.

 When LED number 2 is steady, this indicates an external CAN bus initialization error.

 When LED number 2 is blinking, this indicates message reception on the external CAN bus.

 When LED number 3 is blinking, this indicates that the Serial Communication Card is

communicating with the attached drive. This is only applicable for RDSI systems.

 When LED number 5 is on steady, this indicates there is a serial communication time-out error

(the serial communication was inactive for 1 second). See Section 9 for additional information.

 When LED number 6 is on steady, this indicates that the Serial Communication is in test mode.

 When LED number 7 is on steady, this indicates that the CPU module is sending a drive forward

command. This is only applicable for RDSI systems.

 When LED number 8 is on steady, this indicates that the CPU module is sending a drive reverse

command. This is only applicable for RDSI systems.

4.8 ANALOG I/O MODULE

This section is applicable to the following analog I/O part number(s):

 25-02-074-806E

Outputs:

The four analog output signals are able to send voltage signals from 0 to +/-10VDC, at an 8-bit resolution.

These outputs are for reference voltage only, so each one can only supply 20mA of current. The outputs

share a common ground reference, which is isolated from the Flex M system ground and any additional

I/O card output ground. These outputs can be preconfigured at the factory for different voltage ranges

(ex. 0-5VDC, or 3-6-9VDC).
