Hey Phil! Yes, it’s IEEE 754 standard float, but it seems like Red Lion has some built in mechanism to get 32 bits through a single 16 bit register. I’m not entirely familiar with it, but here’s the link I found the information from - it may make more sense to you than it did me.
As far as more details, here’s what I can think of that is relevant, please let me know what else would be useful.
I’ve tried adding tags both by configuring tag addresses in the gateway and verified with the gateway quick opc client, a single read works but subscribing does not. When I bring in the tags via browsing, it returns 0 (expected is 10.23), and when I assign it to the OPC Read tag group (the only setting I changed was to set data mode to polled), it still returns 0, which is curious. I’m wondering if I’m not missing something in the OPC Read tag group settings.
The other method I’ve tried is creating a new OPC Tag, giving it the address of [DeviceName]1.HRF601 and trying it with both default and OPC Read tag group (same settings from above). This also returns 0.
I’m stuck for the time being, so any ideas are welcome!
