Int/Frac FP
The Integer/Fraction bits are used when the device using the data does not support floating-point
numbers. The first word will carry the integer part and the second word carrying the fractional
part, multiplied by 10000 (giving 4 implied decimal places). Setting this value to 0 uses IEEE
floating point format (default).
Tag Reg 1-5
These values are the registers to be monitored by the Modbus ASCII communications.
Comm 2 Numeric
This button allows the operator access to the DF-1/DNI Menu containing the parameters required
for correct DF-1 Communications. DF-1 Is an Allen-Bradley industrial communications protocol,
which is supported by the MC3 Controller.
DF1 Time-out
This is the delay that will set the DF1 Timeout logical output when DF1 communications have not
been detected.
DF1 Uses BCC (error detection)
This sets the type of error correction for the DF1 protocol. Setting this to 0 will cause the
controller to use the CRC error correction. Setting this to 1 will set the error correction to BCC.
Prtr/0 DF1/1
This selects between using a serial printer attached to Comm Port 1 or using DF1 protocol on the
comm. Port.
RW Protect
The write protection property should be set when a MC³ register is tagged for monitoring only.
When the device writes to words which are write protected, the corresponding Tag n W value
changes accordingly, but the corresponding MC³ register (Tag n R Value) is unaffected.
Byte (Word) Order
The Byte (Word) Order Bit, when set, reverses the order of the two words that contains value
information.
Int/Frac FP
The Integer/Fraction bits are used when the device using the data does not support floating-point
numbers. The first word will carry the Integer part, and the second the fractional part, multiplied
with 10000. (4 implied decimal places).
Tag Reg 1- 5
These are the registers to be monitored by DF1 communications.
NOTE: Please consult Merrick’s Customer Service Department for any questions or comments
regarding the available communication protocols.
Limit Switches
There are several programmable limit indicators available in this controller. They may be
changed during the normal operation of the feeder as required. The Limit Switch Logical outputs
will turn on after the associated delay time. For example, if the High Feedrate limit is set to 50
lb/min and the actual feedrate is 55 lb/min, the output will turn on when the High Feedrate delay
time has expired.
Feedrate
This button allows you to set the upper and lower limits for the feedrate and feedrate deviations.
Setpoint
This button allows you to set the upper and lower limits for the setpoint.
NOTE: When the logical input Limit Setpoint is enabled the setpoint will not be allowed to exceed the
limits.
