Re: grounding noise
I was given a tip on how to fix this. I2C is an open drain bus and needs a pull up resistor on both the clock and signal wires. The tip was to use a 1.5k resistor between the line and a 5v source. Reading a bunch of internet searches others recommended 2.2k-10k resistors. There is a published formul...

Re: quick reconfiguration of temp displays
Thanks. I was guessing that might be the easiest way. I managed to workout curl statements to do this.

quick reconfiguration of temp displays
Any suggestions on quickly reconfiguring temperature sensors? That is my cabinet is wired with 4 of the 7 segment displays. They are usually showing information regarding fermentation. When I switch to brewing fermentation can still go on but I would like to have the displays showing different temp ...

Re: BCS-482 Specifications (replacement for BCS-460/462)
Since the I2C is a Pin Connector, does it provide the 12 vdc + and - ? Yes. You can use the 5 pin jumpers to attach LED displays and power them through the jumper. Much easier connectivity for external external expansion. How many of the LED displays can one safely run from the BCS I2C connector wi...

ladder logic editing
A clear rung button might be nice to clean out a whole rung of test entries.

Re: approach to controlling heating elements
I got the ladder logic working the way I envisioned. I think I had to stop using outputs as rung inputs to themselves as output. I never liked recursion. Out0 is controlled in a process using PID for the HLT. OUT1 controlled with a state using direct on until 200F and then exits to a state that runs...

approach to controlling heating elements
Looking for suggestions on controlling heatings elements. I need to control the HLT and Boil kettle elements, but they shouldn't run at the same time to prevent tripping the circuit breaker. I was trying to use PID to control the HLT; set the boil element on and switch to duty cycle to maintain boil...

Re: circuit protection
I started to convert my rig to electric heating. Here is the start. I will get power from a 30 amp dryer outlet that powers a spa panel with a 50 amp GFCI breaker in it. The BCS will control power with the SSRs.

Re: Float Switch Controlling Output
Why do you care about REG2? I would just use the value of DIN1. The float switch must be floating to have the heating elements on.

Re: I don’t think I’m a idiot, but I have no idea what to do.
I use a 460 to control a freezer/chiller and 2 pumps to control temperature on 2 fermenters. At this point it only uses 1 state and in that state I have the temperature control the power to the cold, and the 2 pumps for recirculation. I have done some stuff with ladder logic and a second state to ad...
