This parameter specifies the maximum permissible deviation between the analog
input values.
•
Permissible values: 0 to 25,000 µA (corresponds to 0 to 25 mA)
(up to hardware upgrade 1.10.1.0: 0 to 21,000 µA - corresponds to 0 to
21 mA)
100
µA
Discrepancy Time 1,
Discrepancy Time 2,
Discrepancy Time 3,
Discrepancy Time 4
This parameter specifies the maximum time for the "Dual-channel evaluation"
function in which the difference between both analog input values is permitted
to exceed the limit value.

Table 20: SafeDESIGNER parameters: SafeCurrentxxyy
The parameters "Limit Threshold High x", "Limit Threshold Low x", "Limit Threshold Equivalent x" and
"Discrepancy Time x" together make up a parameter set. The channels "SafeThrSelector_xxyy_Bit1" and
"SafeThrSelector_xxyy_Bit2" are available in the SafeDESIGNER application to determine which parameter set in
the module is enabled, i.e. it is possible to change the parameter set at runtime.
