Some Toshiba DCS systems use a communications network known as the ADMAP network. Citect has two drivers to this network, the TOSADMAP and JAMI drivers. What is their purpose and when should they be used? 

The TOSADMAP driver is supported under Citect V3 only. This driver requires low level interface software available from CSE Technology, and the AAMI2 card from Toshiba. Due to the computers that Ci Technologies recommend using with Citect, there is a limit to the amount of memory that the computer can have (12MB), which can restrict the performance of Citect.

The JAMI driver is available with Citect V4.2 and Citect V5.x. This driver requires the JAMI1 card from Toshiba which, when used with Citect, supercedes the AAMI2 card. It is highly recommended that the latest Citect version is used for new developments when this driver is used. The JAMI driver is available under Windows NT only, and supercedes the Citect TOSADMAP driver. It is anticipated that the JAMI driver will be released as standard with Citect V5.10. While the JAMI driver will generally communicate with any Toshiba product that can interface to the ADMAP network, the specifics depends on two different modes of communication: Scan and Message. Citect can communicate to the following devices with the Scan and Message modes:

Scan: Any Tosdic product that can read and write scan memory would be able to be handled by Citect.

Message: DPCS (Distributed Process Control Station) and PCS4000/6000 (Process Control Station). To actually communicate with a specific station type such as a DPCS, the specific message formats/types required for that station need to be implemented in Citect. At this stage only the DPCS and PCS4000/6000 message formats/types have been implemented in Citect.
