Programmer Connection at the Remote I/O Scanner

A Logicmaster 90±70 programmer can be connected to rack 0 of a remote drop. (Logicmaster 6 or Logicmaster 5 cannot be used with a remote drop).

Refer to the instructions that follow, for the type of equipment you are using.

HLogicmaster 90 Parallel version and Workstation Interface Board

HLogicmaster 90 Serial version and Workstation Interface Board

HLogicmaster 90 Serial version, no Workstation Interface Board

The Workstation Interface Board can be used for either parallel or serial communications with a remote drop. The board provides ground isolation allowing the programmer ground to vary by up to 500V.

Logicmaster 90 Parallel Version and Workstation Interface Board

If the programmer is equipped with the parallel version of Logicmaster 90±70 and a Workstation Interface Board (IC647WMI920 for Workmaster II or IBM PS/2 computer, or IC640WMI910 for a Workmaster or IBM PC±XT/AT computer), connection is made to a Bus Transmitter module located in the remote drop.

Grounding

For proper operation, the programmer must have a ground connection in common with rack 0. Normally, the common ground connection is provided by connecting the programmer's power cord to the same power source (with the same ground reference point) as the rack. If a common ground cannot be established, use GE Fanuc RS±422 Isolated Repeater/RS±232 Converter IC655CCM590, or an equivalent product.

Connection Instructions

For a Workmaster I or II computer, use cable IC647CBL703.

1.Attach the 37±pin male connector to the computer's Workstation Interface board.

2.Attach the 37±pin female connector to the top connector on the Bus Transmitter module.
