Hardware Setup and Software Installation of PLC Logicmaster

The Work Station Interface (WSI) Board provides a high-performance serial interface between a Series 90-70 PLC and the programmer for the WSI version of Logicmaster 90-70 software. There are two Work Station Interface Boards available; one is for an AT-type computer, and the other is for a PS/2-type computer. 

The WSI Board is included as part of a package with Logicmaster 90-70 programming software. If you have a Workmaster II computer,Guest Posting the WSI board was installed at the factory. For installation instructions on other programming devices, consult the computer manufacturer’s instructions for option boards.

Grounding

Be sure the computer has a ground connection in common with the CPU rack. This is usually done by connecting the programmer computer to the same power source (with the same ground reference point) as the rack.

Cabling

The communications cable that connects the computer to the PLC is a shielded twisted pair cable with a 37-pin D connector on each end. The maximum length for this cable is 50 feet. After installing the Work Station Interface Board in your computer, connect the computer to the PLC by first attaching the cable to the Work Station Interface Board and then to either the SNP port on the CPU module or the parallel port on the Bus Transmitter Module (BTM). If you have the Logicmaster 90-70 version of software which communicates with the PLC using the standard serial communication ports, a serial board with COM1, COM2, COM3, or COM4 must be installed in the computer in order to communicate with the PLC. Refer to GFK-0262, Series 90-70 Programmable Controller Installation Manual, for instructions on establishing a serial connection between the Series 90-70 PLC serial port and the serial port on the programming computer, without having a Work Station Interface Board installed in the computer.

Software Installation

To use Logicmaster 90-70 software, it must be installed on the programmer computer’s hard disk or network disk. The Logicmaster 90-70 installation procedure creates three subdirectories on the hard disk:

1. Software Version: WSI

Subdirectories Created: WSI \LM90 \LM90\P70 \LM90\C70

2. Software Version: Standard serial communications

Subdirectories Created: \LM90\LM90\P70S\LM90\C70S

Refer to the IPI accompanying the specific release of Logicmaster for updated instructions on installation of the Logicmaster software. The information presented in this chapter is not intended to reflect differences in specific releases of the Logicmaster software. Also, please note that you cannot install most versions of Logicmaster.

There is a new version of Logicmaster (IC641SWP716) that was specifically designed as a DOS application that installs. This new version provides SNP or TCP/IP Ethernet communications to Series 90-70 PLCs and uses standard TCP/IP Windows drivers to provide maximum compatibility in a network environment.
