Summary

This document provides information for those converting from obsolete OIT or MAP product to replacement product.

Solution

The following tables illustrate the software used to program each MAP and OIT product.

 Obsolete MAPs1MAP340DMAP460DMAP450A/BMAP450D
MAPware-100XXN/A2X
MAP160X    
1.  Obsolete MAPs: MAP320x, MAP340x, MAP460x
2.  MAP450A/B is obsolete and does not require programming software; programmed in local setup only (B = more memory)

NOTE: If looking to replace your obsolete MAP160 device, the MAP460D is the best upgrade option.

3.  Obsolete OITs: OIT3200A/B, OIT3250A/B, OIT4400A/B, OIT4450A/B, and OIT5400A/B

MAP Products

All obsolete MAP (products prior to the MAP460D) were programmed using MAP160 software. All MAP products are replaced by the MAP460D and programmed with MAPware-100. Only MAP160 projects programmed to communicate with GE 9030, Allen Bradley SLC500, and Omron PLCs can be converted using the 160-Software Conversion Utility (included with MAPware-100).

MAPware-100
MAPware-100 is line based. The MAP Family Operator Interface Terminals communicate with the PLC by reading from and writing to four sets of registers and coils located within the PLC’s internal memory: the Message Request Register (MRR), the Current Message Register (CMR), the Status Bit coils, and the Function Key coils. In addition, the MAP Family Operator Interface Terminals can read from and write to the internal registers and coils in the PLC.

OIT Products

All OIT products are programmed using OITware-200 or STEPware-100. Use the OIT Identification utility in OITware or STEPware to determine the OIT model and what software application was used for configuration.

Convert from one OIT model to another using the Export To OIT feature from the File menu in OITware-200 (not available in STEPware-100).

The obsolete OIT3200B, OIT3250B, OIT4400, OIT4450, and OIT5400 were 40 characters per line displays. The best upgrade option for these OITs is the OIT3600B, as it is the only current product with a 40 character per line display at 2 lines x 40 characters. The OIT4400 and OIT4450 had 4 lines by 40 character displays, and the OIT5400 had 8 lines by 40 character displays. As a result, these OITs do not convert.

OITware-200 is screen-based and used to communicate with a PLC.
STEPware-100 is screen-based and used for ASCII communication (see next page).
MAPware-100 is screen-based and used to communicate with a PLC (MAP320D, MAP340D, MAP460D only).

STEPware-100
The STEP1 Protocol allows the OIT Family and MAP Operator Interface Terminals (MAP320D, MAP340D, MAP450D, MAP460D) to provide the human-machine interface between an operator and an ASCII compatible computer or host controller. Any controller that is capable of sending and receiving ASCII characters through a serial port can potentially communicate to an OIT Family or MAP Operator Interface Terminal using the STEP1 Protocol.

The STEP1 Protocol allows the OIT to receive and send simple ASCII character strings. The OIT accepts:

  • Printable ASCII characters —which immediately display on the OIT
  • Non-printable ASCII control characters (Control Codes) — which directly affect the OIT’s display
  • Special ASCII character combinations (Control Commands)

Control Commands cause the OIT to:

  • Modify the OIT’s configuration parameters
  • Display one of up to 500 predefined messages
  • Sound the OIT’s internal buzzer
  • Sound the OIT’s external buzzer (OIT3250, OIT4450, and OIT5400 only)
  • Turn the OIT’s LEDs on or off (OIT3250, OIT4450, and OIT5400 only)
  • Print to a serial printer (OIT3250, OIT4450, and OIT5400 only)

The OIT can be programmed to send ASCII characters or predefined ASCII strings to the host controller and the OIT’s display. Each of the OIT’s function keys can be programmed with two strings of up to 40 ASCII characters (including ASCII control characters). This allows each function key to simulate an on/off or momentary switch. The OIT’s other keys send individual ASCII characters.

OITware-200
ASCII Slave mode allows the OIT to send and ASCII string to the host (configured in the ASCII Protocol Editor) using a Function Key. The OIT cannot receive an ASCII string and display it. The host can only bring up pre-configured screens using the MRR (Message Request Register).
