Jokab Pluto Safety PLC integreation

khelza · Feb 23, 2016

I have (2) existing machines that I am integrating together with a robot loader/unloader.

Each machine has it's own RT9 safety relay which:
1. has two estops in series into the monitoring channels
2. has an estop and gate switch in series into the monitoring channels
(Yes, shouldn't put safety devices in series - not my design)

I will be integrating the S46 safety PLC but I am unsure how to tie the machines in:
- have relays coming out of the 14 and 24 (power out of K1 and K2 of RT9) with the contacts of those relays going into the Pluto
- or scrap the RT9s and have all safety devices direct wired into Pluto safety PLC
- or ?

Any suggestions will be appreciated!

I'm going to be working with this line soon. If you have time, let me know what you think about the Pluto unit when you're done.

Jokab has pretty good service. Every time I have called them they gave me straight scoop 1st time.
We used them at Cintas for the wash alley. Each had a gate switch as an estop and a machine estop. We did not use the R9.

This will be your choice and from a technical point either will work.
If you have enough Safe Inputs on your Pluto I would get rid of the RT9s and bring everything into Pluto, you may need to add some Tinas too.
As suggested call ABB - Jocab (888) 282-2123 for their recommendations too.

Thanks for your input guys!

I ended up scrapping the two RT9s and putting all safety inputs to the S46 - might as well with all the IO the S46 provides.

Haven't done any programming for it yet, but so far, looks like it won't be too difficult.

My memory is a little fuzzy on this one, are Tina's for single channel inputs?
