The Elliott Flow Micro-4000ZX External Device Interface (EDI) Driver
allows the user to configure bi directional serial communications between
the FactoryLink Real Time Database and one or more Elliott Flow Micro-4000ZX(s),
using the Modicon MODBUS RTU binary protocol. The Elliott Flow Micro-4000ZX
EDI Driver can run on the PC system unit through the standard communication
ports and/or on the IBM Real Time Interface Co Processor (ARTIC) Card. Multiple
device drivers may be installed on the system unit and/or ARTIC card(s) to
communicate with multiple networks.
The Elliott Flow Micro-4000ZX EDI Driver reads and writes data to and
from the Micro-4000ZX(s) through the system unit serial communication ports
or ports on the IBM ARTIC card(s). Read and write operations can occur at
timed intervals, upon triggered conditions, or upon operator or system event
requests. The Elliott Flow Micro-4000ZX 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 Elliott Flow Micro-4000ZX EDI Driver is responsible for
the following data transactions:
Reading data from Micro-4000ZX(s) via single or block read requests.
Writing data to Micro-4000ZX(s) via single value changing or triggered
block write requests.
Announcing any error that may occur for the above two transactions
The FactoryLink Elliott Flow Micro-4000ZX EDI Driver provides the
following configuration tables:
Elliott Flow Micro-4000ZX Station ID Tables use to specify communication
parameters and device specific information per port. Each table consists
of two data entry panels: Elliott Flow Micro-4000ZX Logical Station Control
and Elliott Flow Micro-4000ZX Logical Station Information.
Elliott Flow Micro-4000ZX 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
Micro-4000ZX elements to which data is to be transferred to and from
the FactoryLink Real-Time Database
