Examples of Intra-Station Addressing: Uni-Telway Addressing

At a Glance

With this type of addressing, a master station can access different slaves connected to a bus.

In the following examples, the slaves are connected to the master station (with a Premium processor) via a Uni-Telway bus.

Addressing Rules

In this configuration, the addressing values are as follows:

For the rack address:
- 0 to 7
For the module address:
- 0 to 14
For the channel address:
- 0 if connected via the terminal port
- 0 if connected via a built-in link of a TSX SCY 21601 module
- 1 if connected via a PCMCIA card
For the slave:
- 1 to 98 if the slave is connected to a PCMCIA card or the built-in link of the TSX SCY 21601 module. In this case, the master station can scan up to 98 slaves.
- 1 to 8 if the slave is connected to the terminal port. In this case the master station can scan up to 8 slaves.

CAUTION

UNEXPECTED BEHAVIOR OF APPLICATION

Do not use wrong address parameters. For instance:

Do not set an address parameter that does not correspond to the targeted equipment.
Do not use value greater than 98 in ADDR function (field "e" for the equipment address) when using a TSXSCY21601 or higher than 8 when using a CPU embedded serial port.

Failure to follow these instructions can result in injury or equipment damage.

Connection via Terminal Port

A device with the address Ad0=8 is connected to the terminal port of a Premium.

Address settings of slave 8: ADDR('0.0.0.8')

Connection via TSX SCY 21601 Module

A device with the address Ad0=1 is connected to the built-in link of a TSX SCY 21601 at position 2 in the base rack.

Address settings of slave 1: ADDR('0.2.0.1')
