Heartbeat Verification module
Receive discrete output values from the automation system and transmit discrete input
values from the measuring device to the automation system.
The Heartbeat Verification module receives discrete output data from the automation
system and transmits discrete input data from the measuring device to the automation
system.
The discrete output value is provided by the automation system in order to start Heartbeat
Verification. The discrete input value is depicted in the first byte. The second byte contains
status information pertaining to the input value.
The discrete input value is used by the measuring device to transmit the status of the
Heartbeat Verification device functions to the automation system. The module cyclically
transmits the discrete input value, along with the status, to the automation system. The
discrete input value is depicted in the first byte. The second byte contains status
information pertaining to the input value.
Only available with the Heartbeat Verification application package.
