12.1 Error Diagnosis
The JX2-IO16 module displays the following errors:
• System bus communication - Timeout
• System bus communication - Data buffer overflow
• Error in the output circuit
Response to faults
When an error occurs the JX2-IO16 module will respond as follows:
• The red ERR-LED lights up.
• In Register 3xx0 "Status / Controller" bit 15 "Error" is set.
• In register array element 2 "Error" the corresponding error bit(s) is (are) set.
• The contents of register array element 2 "Error" are automatically entered into the
remanent error history by JX2-IO16 - register array elements 10 - 19.
12.1.1 Error in System bus communication -
Timeout
A timeout exists if the JX2-IO16 module for a specified period does not receive
monitoring messages from the controller via system bus.
The timeout threshold is set using the two register array elements 4 "Communication
- Time base", and 5 "Communication - Multiplicator".
The communication error is deactivated by default. If one of the register array
elements 4 or 5 contains the value 0, no timeout error will be generated.
Once a communication error has occurred, the module is in STOP state. Thus,
without re-initialization it can no longer be addressed, except that control bit 8
"Timeout - Response" in register 3xx0 is set to 0.
Note!
The timeout response of outputs can be defined using register array element 50
"Outputs - Error Mode", and 51 "Outputs - Error Status". For more information
refer to chapter 12.2 "Response of Digital Outputs to Timeout", page 96.
