Activation of messages using simple on/off contacts
The Edwards MCDI Series Text Message Annunciator Driver allows dry contact activation of any Edwards Message Center. It may be used to activate messages loaded in a single message center or a message in multiple message centers. A contact closure instructs the CPU to transmit an activation message to the message center through its RS485 communication output.
OPERATING MODES
Discrete Fixed
Displays messages assigned to a particular contact closure as long as contact is closed.
Multiple messages can run simultaneously
Maximum of 32 messages can be activated from 32 inputs
Momentary Triggered
Displays the message assigned to a particular contact closure until a new message is activated
Maximum of 32 messages can be activated from 32 inputs
Binary Coded Decimal (BCD)
CPU reads the BCD value of inputs I0-I7 and determines the proper message to run.
Maximum of 80 messages can be activated from 8 inputs
Binary
CPU reads the binary value of inputs I0-I7 and determines the proper message to run.
Maximum of 80 messages can be activated from 8 inputs
Counter
CPU refreshes the count each time a command is processed.
Increment/decrement in 1's, 10's, 100's, 1000's or 10,000's
Max value +/- 2, 147, 483, 647
Max of 8 inputs (1 input mod.)
