Programmable Features
Digital Alarms
Alarm on either a 0 or 1.
Analog Alarms
Settings for binary maximum and minimum with the corresponding decimal
maximum and minimum. Setting range for the decimal values is between -9999 and
+9999, values outside of this range are adjusted using the Units setting. High and
low setpoints with hysteresis (1 to 25%).
Comm Watch Alarms
One Comm Watch per unit ID. Poll Fail count in master mode determines if there is
a failure; in slave mode it is the Poll Fail Timer, up to 65530 scaled in sec or min.
*for all alarms above
Latched or momentary operation. 1 to 7 digit DTMF TX code can be used for
signaling applications. Activated by assigning it to one of the 8 groups or disabled.
Totalizers
An analog register can be interpreted as a totalizer (does not alarm).
Units
Applies units to analog alarms and totalizers using a three part selection:
prefix:
none, thousand, million, milli, centi, kilo, mega, giga
measurement:
none, cubic meters, cubic yards, cubic feet, PSI, pounds,
meters, RPM, gallon, barrels, percent, parts per million
rate:
none, per day, per hour, per minute, per second
Coil Output
Used for setting/clearing a bit location in the PLC. 1 to 7 digit DTMF On and Off
codes control the bit setting.
Major/Minor Alarms
Ethernet link failure and e-mail undeliverable can be set as a major or minor alarm.
Protocols
Modbus master or slave, RTU or TCP, Allen Bradley DF1, PLC5 or SLC500 master.
Port Settings
Baud rate: 300, 1200, 2400, 4800, 9600, 19,200, 38,400, 57,600 or, 115,200.
Parity: even, odd, none. Connector: RS232 or RS485.
Communications Timers
(Master mode only) Poll Interval: up to 65530 msec in 10 msec steps.
Poll Timeout: up to 65530 msec in 10 msec steps. Poll Retries: 1 to 5.
Ethernet Port
IP address, subnet mask, default gateway, e-mail server and enable.
Block Addresses
Settings for each Block: the PLC node, the first register address, the type of register:
bit, analog, bit array, comm watch or unused.
