TD 200 Parameters and Messages

You must not use message-enable bits for any purpose other than enabling messages. The

TD 200 requires that you allocate full bytes for message-enable bits.

Note

You can set or clear the message-enable bits from within your program. The TD 200 may

also clear the message-enable bit following an acknowledge or an edit. See Section D.6

for more information.

Edit Password Byte 10 and 11 (Optional)

Bytes 10 and 11 of the TD 200 parameter block store a password that allows you to edit the

configuration of the TD 200 or to change variables. This password is a four-digit integer (from

0000 to 9999). Byte 3 of the parameter block enables the password protection. If you enable

the password protection by setting the password bit in byte 3, you must enter a password in

bytes 10 and 11; however, if you do not enable password protection in byte 3, you are not

required to store a password in bytes 10 and 11.
