5.5.2 System Messages
System Messages display system messages about the EPC.
There are up to 8 (eight) module system messages. Any message will cause the PC interface to
register a module system message. The eight faults are represented by a fault bit number from 0 to
7. A fault condition will be represented by the system message box turning red. In addition, a
triangle with an exclamation sign inside it indicates the specific fault.

Table 23: System Messages
Generally, a module message does not describe a module failure, but communicates that the EPC
is probably configured incorrectly or a temporary fault condition exists.
For instance, the module can be configured to display a system message when the General
Purpose Analog Input is less than 3mA (refer to Section 4.4.1). This condition would result in a
run-time fault being generated. The most probably cause of the Digital Output Error is to
incorrectly connect the output as a digital input.
