Example command:
response:
The analog input module at address DEh has an input value
of FF5D. (The configured data format of the analog input
module is two's complement)
under
over
NOTICE: When modules measure Thermocouple input values that are
outside of their configured range, they will send data that implies out of
bound inputs. The next table shows the return values of the modules;
however, it depends on the configured data format and input value
which may falls under or exceeds the configured range.
An "input out of bounds" warning occurs only when modules are
configured for Thermocouple. Furthermore, the current and voltage
measurement will return to the actual measured input if the readings
fall outside of the configured range!
In the next example, the target module is configured that it has an input
range of T/C type J (Input range: 0 - 760° C) and a data format in
engineering units. The module measures an input value of 820° C.
Example command: #D1(cr)
response: >+9999(cr)
By returning a high value, +9999, the module at address
D1h indicates that the measured input value exceeds the
configured range.
