Key benefits of using SE Systems to write your PLC control software
|
Built-in Diagnostic Messages
These are displayed while the machine is functioning, this tells the operator what the machine is doing and what it is waiting for.
Because our structured method uses the messages in its control, it mean when the machine stops there is always a reason displayed.
The Diagnostic message will generally consist of message number, short description and I/O address, to aid maintenance staff, which reduces downtime.

Interlocks
We use interlocks in both automatic and manual, in automatic we monitor every sensor on the machine and if it changes state at the wrong time
we display a Diagnostic message and drop the machine out of automatic.
In manual we use the interlocks to tell the operator how to get the machine back into the correct state ready for automatic, so with operator having very
little experience he can still re-sequence the machine. Also if the operator tries to operate an invalid or dangerous function the diagnostic message will tell
why this function is not possible.

Step Sequence
At the design stage we sit down with you, the customer and discuss the operation of the machine and from that we will built a spreadsheet, where every action will be allocated a step number.
This will make the machine functions easier for everyone to understand and because we use diagnostic message for every movement and action, there is no need for maintance staff to look or change the ladder logic.
All PLC software is written with built in Diagnostic messages, which reduce downtime.
