If three decimal places are being read in Total 1, and the value is too large to be read with
three decimal places:
I/O (R41,070 – 41,116)
The SF 500 provides I/O in the form of:
•
discrete inputs
•
relay outputs
•
mA inputs*
•
mA outputs*
* The standard SF 500 provides only one mA output (0/4 – 20 mA). The inclusion of an
optional mA I/O card provides two mA inputs (0/4 – 20 mA) and two additional mA
outputs.
For the I/O, the assigned registers represent the logic status (e.g. open or closed) of the I/
O as configured. Discrete inputs are configured via P270, auxiliary input function; while
relay outputs are configured via P100, relay function.
The I/O are mapped into the respective input and output registers, R41,070 and R41,080, as
follows:
For the mA I/O, the assigned registers represent the mA level (e.g. 0 to 20 mA) of the I/O
as registered in P911 and P914, mA output test (output value) and mA input value.
The mA I/O are mapped into the respective input and output registers:
For 0 to 20 mA I/O, the register value ranges from 0 to 20,000. For 4 to 20 mA I/O, the
register value ranges from 4,000 to 20,000. If the 4 or 20 mA values have been trimmed,
