Slice I/O Terminal Introduction
Section 1-1
The status can be checked at the Master using the Off-wire Detection Flag.
This function is valid only for the input ranges 4 to 20 mA and 1 to 5 V.
User Adjustment
Input or output values can be adjusted to compensate for errors in the input or
output voltage or current resulting from the characteristics or connection
methods of the I/O device. Compensation is performed by applying linear con-
version based on the points corresponding to 0% and 100%.
Cumulative Counter
A cumulated value that approximates the integral of analog input or output
values over time can be calculated and read.
Communications Error
Output (Output Units
Only)
The values output by Output Units when errors occur can be set for each out-
put.
Temperature Input Unit Features
Moving Average
Temperature Input Units can calculate the average of the past eight input val-
ues to produce a stable input value even when the input value is unsteady.
Scaling
Scaling allows values to be converted according to the industry unit required
by the user. It reduces the number of operations requiring ladder program-
ming in the Master CPU Unit. Scaling also supports an offset function for com-
pensating for errors in scaled values.
Peak/Bottom Hold
The maximum (peak) and minimum (bottom) values input to Temperature
Input Units can be held. These values can then be compared with alarm set
values, and flags turned ON accordingly to indicate the status (comparator
function).
Top/Valley Hold
The top and valley values for values input to Temperature Input Units can be
held. The timing of tops and valleys can be monitored with the Top/Valley
Detection Timing Flags. The top and valley values can be compared with
alarm set values, and flags turned ON accordingly to indicate the status (com-
parator function).
Rate of Change
The rate of change for values input to Temperature Input Units can be
obtained for each sampling cycle.
Comparator
Values input to Temperature Input Units or values after math processing can
be compared to the alarm set values (HH, H, L, and LL), and the result indi-
cated with the Temperature Status Flags. If the result is outside the set range,
the Normal Flag (pass signal) is turned ON.
Off-wire Detection
With Temperature Input Units, disconnections can be detected individually for
each sensor input. The status can be checked at the Master using the Off-
wire Detection Flags.
Input Error Detection
Disable
Detection of input errors, including off-wire detection, can be disabled for
channels that are not used.
User Adjustment
Input or output values can be adjusted to compensate for errors in the input or
output voltage or current resulting from the characteristics or connection
methods of the I/O device. Compensation is performed by applying linear con-
version based on the points corresponding to 0% and 100%.
Cumulative Counter
A cumulated value that gives the integral of analog input values over time can
be calculated and read.
Top or Valley Count
The numbers of times that the top or valley value is reached can be counted,
e.g., in an application in which the temperature input value varies in a fixed
cycle of temperature change. The host will be notified with a flag when the
number of cycles exceeds the set value.
