SSEMBLY
The following parameters are used in the input assembly of the module:
Parameter Datatype Description
Instance STRING The instance name of the module that was configured under the
general DF1 configuration in the PLX50 Configuration Utility.
Status.Reserved BOOL Reserved
Status.ReactiveTagMode BOOL Set if the module is operating in DF1 Slave mode.
Status.ScheduledTagMode BOOL Set if the module is operating in Scheduled Tag mode.
Status.ConfigurationValid BOOL Set if a valid configuration is executing in the module.
Status.RoutingInhibited BOOL Set when the module’s routing function has been inhibited. Routing
can be inhibited by setting a bit in the output assembly of the module.
Status.ScheduledTagStatus0…19 BOOL[20] Each bit represents the status of the last scheduled transaction for
that specific map item. A true value indicates success.
TransactionRate DINT The transaction rate is the number of DF1 messages per second that
the module is currently routing.
DeviceTemperature REAL The internal temperature of the module.
DF1RxPacketCount DINT The total number of DF1 packets received by the module.
DF1TxPacketCount DINT The number of DF1 packets sent by the module.
DF1ChecksumErrors DINT The number of corrupted DF1 packets received by the module.
PCCCRequests DINT The total number of DF1 message routing requests received by the
module when operating in Bridge mode.
PCCCFailures DINT The total number of DF1 message routing requests that resulted in
errors when operating in Bridge mode.
TagReads DINT The total number of tag reads executed by the module when
operating in Tag Map mode.
TagWrites DINT The total number of tag writes executed by the module when
operating in Tag Map mode.
TagConnectionFailures DINT The number of failed class 3 connection attempts when operating in
Tag Map mode.
Tag reading and writing requires the module to first establish a class
3 connection with the Logix Controller.
TagErrors DINT The number of failed tag access (read/write) requests when operating
in tag Map mode.
These may include privileged violations, non-existing tags, etc.
