MTI DOC 91795-A1
1
DESCRIPTION
The 91795 Embedded Controller builds on MTI’s proven PLC2000 series controller platform.
The Embedded Controller was designed with large, distributed systems in mind while
maintaining MTI’s cost effectiveness for systems of all sizes. All communications are performed
over the Ethernet port which allows the 91795 to be located anywhere on the control network.
This provides great flexibility in system design and implementation. The Embedded Controller
supports up to sixty-four processors. Each processor can control up to sixty-four I/O points
which means that the 91795 can support up to 4,096 I/O points. The 91795 is configured using
MTI PLC Software or the web browser interface.
The controller can perform 100+ predefined functions as single line instructions. The controller
allows for script language programming for special functions. The operating system is stored in
flash memory for easy programming. The Embedded Controller communicates with the MTI
91620 data loop converter to provide control of all MTI data loop devices. The 91795 also
communicates with the MTI 81750 Decoder Board which provides Ethernet communications
directly from the 91795 to the I/O termination boards. All control communications have the
option of full encryption through the use of Secure Socket Layer (SSL) protocol. This protocol
provides a standards-based method of encryption with low overhead and latency. All networked
components of the MTI control system can be configured to utilize this protocol for
communications.
