When ASRTU-EC16AP is disconnected from the master or exits from the OP
state, users can set up the output values for local output points, the first 8 digital
modules and the first 8 special modules with the parameters "COMlost_RTU_
Output", "COMlost_DOmodule1_Outputs" to "COMlost_DOmodule8_Outputs"
and "COMlost_AOmodule1_Outputs" to "COMlost_AOmodule8_Outputs". And
the output for other modules will be cleared.
When ASRTU-EC16AP is disconnected from the master or exits from the OP
state, the output values after disconnection can be set up with the parameters
CR124~CR132 of the right-side modules (ASRTU-EC16AP firmware V1.02.00
and later versions support this function.)
1. CR124 is used to set the output mode of a right-side module after
disconnection. When CR124 is set to 0 and ASRTU-EC16AP disconnects
from the master or exits from the OP state, the right-side module will output
according to the values in CR125~CR132; When the value in CR124 is not
0 and ASRTU-EC16AP is disconnected from the master or exits from the
OP state, the right-side module will maintain the current output.
2. Each module on the right side of ASRTU-EC16AP has its own
CR124~CR132. Users can set the output status of different modules with
CR124~CR132 of each module when ASRTU-EC16AP is disconnected
from the master or exits from the OP state.
3. When ASRTU-EC16AP is disconnected from the master or exits from the
OP state, local output points will still output the value of the parameter
"COMloss_RTU_Output".
4. In this mode, the parameters "COMlost_DOmodule1_Outputs" ~ "COMlost_
DOmodule8_Outputs" and "COMloss_ AOmodule1_ Outputs" ~ "COMloss_
AOmodule8_Outputs" will be automatically cleared to 0.
When ASRTU-EC16AP is disconnected from the master or exits from the OP
state, the output values of the local output points, the right-side special modules
and digital modules are the same as they are before disconnection.
When the actually connected right-side extension modules are inconsistent with
those configured on the software, ASRTU-EC16AP will not enter the OP status.
When the actually connected right-side extension modules are inconsistent with
those configured on the software, ASRTU-EC16AP is allowed to enter the OP
status.
The Error LED indicator of ASRTU-EC16AP blinks when an alarm occurs to
right-side modules.
There is no change to the Error LED indicator of ASRTU-EC16AP when an alarm
occurs to right-side modules.
