Eurotherm Controls EM-2 EDI Driver

The Eurotherm Controls EM-2 External Device Interface (EDI) Driver allows the user to configure bi directional serial communications between the FactoryLink Real Time Database and the Eurotherm EM-2 via the Eurotherm Control Master (ECM) Allen-Bradley Gateway. The Eurotherm Controls EM-2 driver supports the Allen-Bradley Data Highway Plus binary protocol and provides the means to convert the integer formatted data to and from floating point values without the use of the Math and Logic task. Multiple device drivers may be installed on the system unit to communicate with multiple EM-2 Gateways.

Read and write operations can occur at timed intervals, upon triggered conditions, or upon operator or system event requests. The Eurotherm Controls EM-2 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 Eurotherm Controls EM-2 EDI Driver is responsible for the following data transactions:

• Reading data from EM-2(s) via single or block read requests.
• Writing data to EM-2(s) via single value changing or triggered single or block write requests.
• Convert integer data read from EM-2 to floating point and vice-versa for writes
• Announcing any error that may occur for the above two transactions.

The FactoryLink Eurotherm Controls EM-2 EDI Driver provides the following configuration tables:

• Eurotherm Controls EM-2 Station ID Tables use to specify communication parameters and device specific information per port. Each table consists of two data entry panels: Eurotherm Controls EM-2 Logical Station Control and Eurotherm Controls EM-2 Logical Station Information.
• Eurotherm Controls EM-2 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
  • EM-2 parameters to which data is to be transferred to and from the FactoryLink Real-Time Database
