Controller 740

(еК2.390.419)

The controller contains powerful computing resources in the absence of an operating system: The module is designed for use in control and recording systems, digital signal processing systems with high demands on speed, volume of data processed, reliability and fault tolerance as a computing and control node.

The module receives, processes data from intelligent modules and transmits control actions to the I / O control modules via CAN and RS-485 networks.

Controller software

The controller is programmed in C language in the Keil environment. An example of the program using all the features of the controller and a detailed description of the program is on the site. If necessary, according to the relevant terms of reference, it is possible to develop the necessary software.

The controller is programmed via the RS-232 service interface. The programming cable is included in the delivery. There is a special software that allows you to view in real time up to 256 bytes of any memory controller and set the values ​​of program variables.

It is possible to reprogram the CAN (the programming algorithm is given in the programmer’s manual) using a buffer transmission.

Example of using module 740

Connector circuit of the module
Схема разъемов модуля 740

To connect the termination resistor CAN1, it is necessary to install a jumper between pins 22 and 23.

To connect the termination resistor CAN2, it is necessary to install a jumper between pins 30 and 31.

To connect the termination resistor CAN3, you need to install a jumper between pins 13 and 14.

To connect RS-485, you need to install a jumper between pins 17 and 19.

Connection to the contacts of the module by plugs with spring terminals type FKCT 2,5 / 4-ST from PHOENIX CONTACT (it is allowed to connect single-core and stranded wires with a cross section from 0.2 to 2.5 mm2).

The necessity of completing the module with plugs is specified when ordering.
