The base address for screen 522 FREQOT CHANNEL is 529, item 1024.
Table 26: Screen 522 Frequency Output block Channel #1
Item# Parameter Name Parameter description
0 STATUS Enter an even number to turn on block. Enter an odd number to turn off block.
Enter 10 to force block to use internal limits rather than Product Code table
limits
1 COUNTER
INITIALIZE Equals 1 if counter that connects to this block was previously initialized. Power
loss may require re-initialization of counters. Enter 0 to re-initialize and the
computer changes to 1
2 SPARE
3 DATA POINTER Pointer to address of output data location
4 LOW LIMIT Value of data from the data pointer that gives minimum analog output—4mA or
0V
5 HIGH LIMIT Value of data from data pointer that gives maximum analog output—20mA or
10V
6 OUTPUT COUNTS Count value actually sent to counter. See description below
7 RANGE SELECT Enter 0 to select 4–20mA range. Enter 1 to select 0–20mA range. Use screen
#63 to setup
