The Analog Devices uMAC MCComm External Device Interface (EDI) Driver
allows the user to configure bi directional serial communications between
the FactoryLink Real Time Database and one or more Analog Devices uMAC-1060,
uMAC-5000 and/or uMAC-6000, using the MCComm ASCII protocol. Multiple device
drivers may be installed on the system unit to communicate with multiple
networks.
Read and write operations can occur at timed intervals, upon triggered
conditions, or upon operator or system event requests. The Analog Devices
uMAC MCComm EDI Driver controls the communication interface through information
designated by the user in multiple configuration tables accessed from the
FactoryLink Configuration Manager utility.
The FactoryLink Analog Devices uMAC MCComm EDI Driver is responsible for
the following data transactions:
Reading data from uMAC(s) via single or block read requests.
Writing data to uMAC(s) via single value changing or triggered block
write requests.
Announcing any error that may occur for the above two transactions.
The FactoryLink Analog Devices uMAC MCComm EDI Driver provides the
following configuration tables:
Analog Devices uMAC MCComm Station ID Tables use to specify communication
parameters and device specific information per port. Each table consists
of two data entry panels: Analog Devices uMAC MCComm Logical Station Control
and Analog Devices uMAC MCComm Logical Station Information.
Analog Devices uMAC MCComm Read/Write Tables use to identify the following:
FactoryLink Real Time Database elements to be used as read and/or
write triggers
Whether or not exception writes are to occur
FactoryLink Real Time Database elements to be used as table status indicators
uMAC data elements to which data is to be transferred to and from the
FactoryLink Real-Time Database
