Figure 35 Channel Data From Menu
4.5.3.2.1 Min an Max Raw
Min Raw and Max Raw counts entries included in Input Data From: menus define the range of input counts
that provide Measurement Range read-out values. This menu entry is determined by the A/D converter
resolution of the channel’s input. For example, if the input is a 10 bit Modbus® device with zero at 200
counts and 100% at 1000 counts, then this menu’s MIN should be set at 200 and MAX at 1000. If
communicating with the ViewSmart 1600+’s optional 12 bit Analog Input PCB the MIN should be 800 and
the MAX 4000.
If the input device’s resolution is unknown, the live counts variable on the Combination screen displays
actual raw A/D counts currently being read by this channel. This reading may be used to test the input
device for what A/D counts are provided for zero and 100% if these values are unknown. Forcing the input
device to read zero should provide the A/D counts value needed to make this channel’s display also read
zero. Likewise, forcing the input device to read 100% should provide the A/D counts value needed to make
the ViewSmart 1600+ channel’s display also read 100%.
Note: Each
Data From
: item has a matching default Min/Max counts value of 20% to 100% with ± 5%
over/under range applied. If the default value is incorrect for the input device it should be edited.
4.5.3.2.2 Remote ID
When the Data From is set to receive input through the Communications ports, this is where the salve’s
unique ID number is entered. Remote ID numbers up to 247 are valid.
4.5.3.2.3 Alias
The Alias register numbers define the location of the variable representing the input value of the Modbus®
data received through the Communications ports. This number must be obtained from the manufacturer
of the Modbus® RTU device.
4.5.3.2.4 Function Code
The Function Code is the code used to write configuration parameters to the Modbus® registers. Modbus
registers and write codes are discussed in detail in Appendix 3.
