Meldas M3 parameter reinstall

Initialize the MC-161(9) card
– In the back cabinet, find the MC-161(9) card on the control.
– Locate the DIP switches along the edge of the MC-161(9) card.
– Starting from the topmost switch, flip the first, third, and fifth switches on.
– Turn on the main disconnect, then turn on the control for 30 seconds. The screen will still be blank.
– Power everything off and set all the DIP switches back to the left/off positions,
– Power up the control again.
– You should now have a display.

Format the memory and load the canned cycles
– Go to the ALARM/DIAG screen and press the soft key for PLC-I/F.
– At the bottom of the screen in the first three fields, enter 1001 in the DEVICE field, leave DATA empty, and M in MODE and press input.
– Go to the TOOL/PARAM screen, and press the soft key for BASE2
– Change fix_P to have a value of 1.

Set I/O parameters to transfer machine parameter file
– Go to TOOL/PARAM screen
– Use NEXT soft key twice to show I/O PARAM and press the soft key for it.
– On the first screen, we only care about the first three for DATA IN, DATA OUT, and NC RUNNING. Set them all the same for now. Set DEVICE to 0. Set PORT to 0 or 1. This depends on how the machine builder set things up. If you’re not sure, set PORT to 0 and plug your RS-232 cable directly into the port on the MC-161(9) card.
– Press the soft key NEXT to get to page 2/5.
– There are three fields to enter data. The first is for the DEVICE you are communicating with (in case you want to use different settings for simple transfer and DNC modes), the second field is the parameter #, and the last is the value of the parameter.
– I set my machines with the following:
– These settings will run 9600 baud, 7 data bits, even parity, and 2 stop bits.

Code:
DEVICE NAME XON
BAUD RATE 1
STOP BIT 3
PARITY EFF 0
EVEN PARITY 0
CR. LENGTH 0
TERM TYPE 0
TERM CODE1 0
TERM CODE2 0
REWIND CODE 0
HANDSHAKE 3
DC CODE PARITY 1

Transfer the parameter file to the machine
– Get your PC ready to transfer.
– Go to PROGRAM/IN/OUT and press the soft key IN/OUT.
– Press the soft key for INPUT.
– In the # ( ) field, enter 3 and then cursor over to the DATA field. Leave it blank and press the input key. If the PC is ready and the RS-232 cable is correctly wired, the control will be waiting for data.
– Go back to the PC and initiate the transfer.
– When all the data is in, press RESET.
