1. WS3000 TABS Description
The Serial WS3000 TABS driver allows the FieldServer to transfer data to and from devices
over either RS-232 or RS-422 using WS3000 TABS protocol. The FieldServer can emulate
either a Server or Client.
The WS3000 TABS driver is set up for Alarm Surveillance and Control. The protocol works over
a multidrop RS-422 line or over a RS-232 line and allows only one master and up to 32 slaves
on a serial channel. Slaves are assigned station addresses that range from 0 to 31. The master
does not have a station address. The protocol is strictly command/response with the master
polling the slave devices. Each slave can be configured to hold the data for one to 256
displays. Each display contains 64 alarms status points represented by bits.
This driver only supports short addressing mode, thus allowing for a maximum of 256 displays
per tabs device.
The Server driver fully supports the processing of the following AS&C Remote Control
Commands:
Type 0, 1, 2, 128-255
The Client driver supports the sending of AS&C Remote Control Commands (writes).
