HMI Systems J1939 Switch Pack

[Jeremy Kopicz]

Attached is the block to use the ifm controllers with ED&D Switches and a sample config file for the EDD Switch. You will need to configure the transmit and receive message ID's based on your needs. This is compatible for firmware versions 5 and above. Not tested w/ 32 bit controller.
Libraries Used:
J1939_2_v050001
Controller Library v050001 (Can 2 transmit in extended mode)

For EDD on CAN 1:
J1939_1_v050001
CAN1_EXT_v050001

A custome data type is used for the colors of the switches. Available colors are:
OFF
RED
GREEN
BLUE
YELLOW
CYAN
WHITE
MAGENTA

Use these values for the inputs SWx_LED_TOP/BOTTOM.

EX: Use a SEL block to select between 'OFF' and 'GREEN' to toggle an LED based upon the input of the SEL statement. I left the block without this function so you have the ability to use more than 2 colors at a time.

Do you know what the default PGNs are for the edd switchpack that you sell? (Basically, how would I get it to work out of the box without using the configuration tool?)

[Jeremy Kopicz]

They won't, they don't have any configuration out of the box. There is no data mapping, no message setup etc. You must put in a configuration. The one supplied here will work with our function block. Problems would arise if there is more than one switch pack in a system since they would need different SA or PGN's.

[Jeremy Kopicz]

Attached is a new HMI Systems Rocker switch interface for ifm 32 bit controllers and rocker config sample.

You can set the number of switches, LED PGN and Button PGN in the HMI_SYS_VARS global var list.

This export is set for can 3. You can change the can bus in the HMI_SYS_ROCKER_INTERFACE POU and the HMI_ROCKER_COMMS data type.
