DESCRIPTION

Enter a descriptive name for this PLC_DEF as it is being used. The description can be up to 50

characters.

STATION

ModbusB slave address set via the DIP switch labeled S1 on the SHIM. Valid entries are 1

through 31 regardless of whether the SHIM is connected to an MVI serial I/O port via RS-232

directly or through the converter for RS-485.

The field range is from 1 to 255 (in decimal).

Default = 0.

BACKUP STATION

This is the back-up station address. An address of zero(0) means that there is no redundancy.

The field range is from 1 to 255 (in decimal).

Default = 0.

Leave blank for SHIMs.

PLC DEVICE TYPE

This is the definition of the smart device manufacturer and model that is attached to the port.

The acceptable smart device types are defined in the PLCTYPES reference templet that is

defined as part of the PLC_DIR for the data base to use. Please see Section A.1.4, PLCTYPES

Initial Data Base for more information on the reference templet.

Acceptable PLC DEVICE TYPES are:

•SHIM <- used for SHIMs.

•AB_SLC504

•AB_PLC2

•AB_PLC3

•AB_PLC5

• MOD_984

• GENERIC (for non-specified devices)

MAX READ LATENCY

This is the maximum time allowed between read commands. This is how long the scanner will

wait before forcing a set of reads to occur. When the time expires a read is placed at the

beginning of the output queue.

The fields range is 5 to 500 seconds

Default = 10.

Enter 10 for SHIMs.
