9.5.1.3 Explanation of special functions and module state bits
Attention: Functions and module state bits depend on the used SW version
HW_ENABLE The „Enable” signal (HW Enable pin 8d) is activated at the module.
ERROR An Error has occurred in the DAC-4x(A). Different possible problems can cause this. Please refer to the manual
for the according DAC-4x(A) version.
BUS_DISABLE Enable signal was reset by means of Profinet (DAC-4x(A) is disabled).
Switching off the HW enable also resets any pending BUS_DISABLE
Din_1 To enable the function for the „remote loop controller” (function switches from open loop to closed loop) via the
comparator „Comp_1” is enabled and can be used. Additional mandatory condition: C1.00 must be set to 2 or 4!
Remark: d1.12 and d1.13 remain at „0.000 V” as long as the condition for activation „Din_1“ has not be set. This
will prevent a premature activation of the comparator „Comp_1“.
Dout_1/CL Indicates that the function „loop controller” for the branch 1 is active. When the module is working in „remote
loop”, the module is now working in closed loop mode. Additional mandatory conditions for transition from open
loop to closed loop:
• C1.00 must be set to 2 or 4
• Signal Din_1 must be present
• Comparator Comp_1 has to be outside of the window, hence signal Comp_1 = 0.
The module will remain in closed loop operation as long as signal Din_1 stays on „High”.
Comp_1 Output signal of comparator „Comp_1“, s used in order to monitor the signal defined by C1.25.
This signal can also be used in order to switches over from open to closed loop:
0 = comparator is not active (out of the determined limits and time delays)
1 = comparator is active (inside the determined limits and time delays).
Comp_11 Output signal of comparator „Comp_11“, is used in order to monitor the signal defined by C1.32
0 = comparator is not active (out of the determined limits and time delays)
1 = comparator is active (inside the determined limits and time delays).
Din_2 To enable the function for the „remote loop controller“ (function switches from open loop to closed loop) via the
comparator „Comp_2“ is enabled and can be used. Additional mandatory condition: C2.00 must be set to 2 or 4!
Remark: d2.12 and d2.13 remain at „0.000 V“ as long as the condition for activation „Din_2“ has not be set. This
will prevent a premature activation of the comparator „Comp_2“.
Dout_2 Indicates that the function „loop controller” for the branch 2 is active. When the module is working in „remote
loop”, the module is now working in closed loop mode. Additional mandatory conditions for transition from open
loop to closed loop:
• C2.00 must be set to 2 or 4
• Signal Din_2 must be present
• Comparator Comp_2 has to be outside of the window, hence signal Comp_2 = 0.
The module will remain in closed loop operation as long as signal Din_2 stays on „High”.
Comp_2 Output signal of comparator „Comp_2“, s used in order to monitor the signal defined by C2.25.
This signal can also be used in order to switches over from open to closed loop:
0 = comparator is not active (out of the determined limits and time delays)
1 = comparator is active (inside the determined limits and time delays).
Comp_22 Output signal of comparator „Comp_22“, is used in order to monitor the signal defined by C2.32
0 = comparator is not active (out of the determined limits and time delays)
1 = comparator is active (inside the determined limits and time delays).
TST_CMP This bit can be used to test the Set Error/Comp output. When set, the output is set to 24V, independent of the
Comp_1/Comp_2 signal. To activate this function the parameter E 18 must be set to a value > 0 and no error is
present.
