Infra Red PLC 540 to Control Logix

[Tyke61]

I have an application involving an existing PLC 540 located in a master panel to a new controllogix system on a mobile crane. The previous system had a PC on the crane and a bespoke infra red link was used for simple comms. Does anyone know of a supplier of a manufacturer of a device to communicate between the PLC systems over infra red using standard protocols such as DFI or ideally DH+ ?

This brochure from SICK (http://www.sick.com/home/products/product_start/factory/industrial_sensors/en.toolboxpar.0002.file.tmp/product_overview_industrial_sensors.pdf) mentions the ISD 300 (on page 37). It can optically transmit data via DH+.

For DF1 I think that a wireless solution must be possible from several vendors.
