watch list binary,set on 1 off 0

All pre written oven control program with 10 cook steps

The 1's occasional revert to 0 for no apparent reason.

example:

Step 1

High fan = 1
low fan = 0

Intake damper = 1
exhaust damper = 1
Burner = 1

step 2...etc

Thanks Dan

That's not the issue. The question posted has to do with watch list binaries.

loss of ip through data packet collision (in milliseconds) might be causing the preset binary drop out to my plc's
in Mango watch list, not sure yet...

Hey Joel,

I am wondering why my binaries drop out occasionally in my ten step program (with steps per step) in the watch list.

Mango is all modbus ip to some plc's. Would a packet collision cause this on the plant wide intranet/internet

I am having to go and "set" my 1's (reset) as they occasionally just zero off for no apparent reason

This is a mission critical issue...

Thanks, Charlie

Hey Joel,

What causes dos to open and then close when trying to boot up in ma-start ?
Do i need to modify something in java?

Thanks, Charlie :oops:
