1. GE- SRTP Driver Description

The GE -SRTP driver allows the FieldServer to transfer data to and from devices over Ethernet
using GE -SRTP Driver protocol. There are two Ethernet ports standard on the FieldServer. The
FieldServer can emulate either a Server or Client.

The GE -SRTP driver is capable of read & writing the data tables of a GE series 90 PLC which is
equipped with an Ethernet port.

The driver is capable of exposing its communication statistics so that they can be monitored by a
downstream device.

3. Hardware Connections

Make sure the device IP_address is configured to be on the same IP network as on the
FieldServer. Use a crossover cable if the FieldServer is connected directly to the PLC
device. Use a straight cable if the FieldServer is connected to a hub.

4. Configuring the FieldServer as a GE- SRTP Driver Client

For a detailed discussion on FieldServer configuration, please refer to the instruction manual for the
FieldServer. The information that follows describes how to expand upon the factory defaults
provided in the configuration files included with the FieldServer (See “.csv” files on the driver
diskette).

This section documents and describes the parameters necessary for configuring the FieldServer to
communicate with a GE -SRTP Driver Server.

The configuration file tells the FieldServer about its interfaces, and the routing of data required. In
order to enable the FieldServer for GE -SRTP Driver communications, the driver independent
FieldServer buffers need to be declared in the “Data Arrays” section, the destinatio n device
addresses need to be declared in the “Client Side Nodes” section, and the data required from the
servers needs to be mapped in the “Client Side Map Descriptors” section. Details on how to do this
can be found below.

Note that in the tables, * indicates an optional parameter, with the bold legal value being the
default.

4.1 Data Arrays

Section Title

Data_Arrays

Column Title Function Legal Values

Data_Array_Name Provide name for Data Array Up to 15 alphanumeric

characters

Data_Format Provide data format. Each data array can only

take on one format.

Data_Array_Length Number of Data Objects. Must be larger than

the data storage area required for the data
being placed in this array.

Example

// Data Arrays

Data_Arrays
Data_Array_Name, Data_Format, Data_Array_Length
DA_AI_01, UInt16, 200
DA_AO_01, UInt16, 200
DA_DI_01, Byte, 200
DA_DO_01, Byte, 200

FLOAT, BIT, UInt16, SInt16,
Packed_Bit, Byte,
Packed_Byte, Swapped_Byte
