Note Using ambiguous Types makes the operator, or overriding control system, responsible for
supplying the identifiers in the expected order.
The values of the Identifier Types included in the Work Order are not available to the Station as long as
the Work Order is
active . On completion, all Identifier Types of the Work Order are sent to the Station and
its PLC.
Should the Work Order become active again after completion (by receiving the first Type in the list) then
all Identifier Types of the Work Order are reset.
The values of the Identifier Types which are not included in the Work Order are available to the Station
and PLC immediately when accepted.
The Multiple identifier function is reset, meaning that the values of all Identifier Types are cleared, when a
cycle is started from the PowerMACS PLC. That is, accepted identifiers can only be used once. To include
them in a following cycle their respective source must be initiated to generate the string again.
Result variables
To include the data of an Identifier Type string in the result data it must be mapped to one of the six
Result variables . Each of these result variables is represented in the cycle data by one of the for Station
level result variables "ID Res 1" to "ID Res 6" (all 40 character strings):
This is done by selecting the wanted Identifier Type as source for a particular result variable in the Result
variables frame. One Identifier Type can be used as source for more than one result variable.
Use the optional Significant position filter to select which character positions of the Identifier Type string
to transfer to the result variable.
The values of the result variables are sampled when the cycle is started from the PLC.
