Operation at error detection
When the discrepancy state of double inputs continues for the set time or longer, the double input discrepancy detection error
(error code: 0203H) state is applied to the safety remote I/O module, and the corresponding input point is turned off. For the
error state, refer to the following.
Page 118 Error codes related to the safety remote I/O module
When an error occurs for all the input points due to the input dark test error (error code: 0204H) or double
input discrepancy detection error (error code: 0203H) and the input function cannot be performed anymore,
an I/O data error (error code: 0108H) results. However, when a double input discrepancy detection error (error
code: 0203H) occurs while "1: Used" is set for "Double input discrepancy auto recovery setting", the input
function may be recovered. Thus, an I/O data error (error code: 0108H) does not occur even if the error
occurs for all the input points.
■
Setting method
Set the double input discrepancy detection setting in "Double input discrepancy detection setting" from the "Parameter of
Slave Station" window of the engineering tool.
*1 n: Even number of 0 to 6
• When an item other than "1: Safety double wiring (NC/NC)" is selected in "Wiring selection of input", the
"Double input discrepancy detection setting" parameter is ignored.
• When double input discrepancy errors do not need to be detected during equipment maintenance including
system start-up and inspection, select "1: Do not detect".
