SETTING UP A SYSTEM

Setting up a SB system includes the following steps:

1. Verify that existing MCs are equipped with a RS-485 Serial Ports and have software

application versions listed in Model Specific Information (page 27). If not, complete and/or

upgrade.

2. If an A-B 1771-DXS2 processor is used, locate a PLC-5 to serve as a host for the 1771-

DXS2 Information Processor and 1771-DXKT adapter (if applicable). Two slots must be free,

and the power supply must be able to handle an additional 5V load of 1.6 A, -12V load of

0.04 A, and a +12V load of 0.04A. Install according to instructions in [1], page 2-2.

3. If an A-B 1771-EIP processor is used, locate a PLC-5 to serve as a host for the 1771-EIP

Information Processor. One slot must be free, and the power supply must be able to handle

an additional 5V load of 2.2 A, -12V load of 0.04 A, and a +12V load of 0.04A. Install

according to instructions in [8].

4. If a generic personal computer (PC) will be used, make sure all required hardware is

installed. This may include a 1784-KT/B or 1784-KTX card, and a RS-422 adapter. See

Install the KT Card (page 4), or Install the KTX Card, if used (page 4) and Install RS-422

converter or adapter, if needed (page 4).

5. Copy the SB software files to the PC hard disk and modify the PC configuration files if

necessary. See Modify PC configuration (page 5).

6. Assign a DH+ or DH485 station number for SB. See Assign Station Numbers (page 9).

7. Verify that SB starts up properly in the PC. See Verify SB startup (page 9).

8. Connect all MCs to SB. See MC Physical Connection (page 10).

9. Set up communication parameters in all MCs connected. See Setting Up communications

with the MCs (page 10).

10. Configure SB for the number of MCs connected. See SB Configuration for MCs (page 11).

11. Verify that communications with the MCs work properly. See Verify MC communication (page

11).

12. If data is to be copied from SB to one or more PLC, the file copy scheme must be set up and

verified. Use the steps 13..16.

13. Allocate memory files in the PLC(s) to hold SB data. See Allocating A-B files (page 12).

14. Configure SB to read and write the A-B files. See SB Configuration for File Copy (page 12).

15. Connect SB to your DH+ or DH485 network. See Connecting SB to DH (page 13).

16. Verify that the file copy process works properly. See Verify A-B File Copy (page 13).

17. If SB is to service PLC-2 type Unsolicited Messages, that is, act as a PLC-2 with respect to a

MMI or other PLCs on the DH+ network, some PLC-2 parameters have to be set-up. See

Setting up PLC-2 Compatible parameters (page 13).

18. Verify that the Superbridge version is compatible with the MC application software version.
