Anybus CompactCom M40 User Manual

Appendix A: Implementation Examples 45 (114)
A.4 8–bit/16–bit Parallel
This example shows a design for 8-bit and 16-bit parallel mode. Using M30 you have access to
8-bit parallel and serial modes. With M40 you can also use the 16-bit parallel mode.

If LEDs are to be used in the host application, please refer to Network Status LED Outputs
(LED[1A...4B]), p. 48, for guidelines on how to connect the LED outputs. In 16-bit parallel mode
it is not possible to use these outputs for LEDs.
In this implementation, the LED outputs on the Anybus CompactCom M30 module are
protected by external circuitry (74B3T3245, a SN74CB3T3245, 8-BIT FET BUS SWITCH is
suggested). This circuit is fast, and only lets the signal from the driving circuit pass through.
