Technical support / 0-1V or 0-5V?
« on: March 30, 2010, 10:08:00 AM »
Hi.

I think I have seen that MD Plc can have 0-1V or 0-5V analogue signal input for ADC. Am I right? Or is 0-5V the preferred analogue signal?

I need the MD Plc to drive a VFD that takes either 0-20mA, or 0-10V input as control for speed of the motor. Any way to achieve it?

How can I make a MD Plc retrieve a DM value from another MD Plc? Connect both of them using RS485?

Thanks
Regards

so do u mean that once the ladder logic is uploaded into the plc memory, there is no mistake? there'll not be any noise uploaded together to make the plc mulfunction at times?

Bought a T22H-npn and programmed it. transferred the ladder logic to the plc using winME command prompt window. Will that render erratic behaviour for the PLC? Tried troubleshooting the ladder but everything seems alright. The automation works alright but except for occasional glitch.
As for the sequencer in the program, what and how do you use it? for what sort of functions? can't i use normal ladder programming ways to achieve that of the sequencer?
What about relays and latching relay in the software? very confused about all the term as i'm new.
