3-16 Chapter 3 Variables
9.12 Serial word output
Outputs to the serial output word information or indicates the output status.
Format
SOW(m)
Values m : port number .................... 2 to 15
The output range is 0 (&H0000) to 65,535 (&HFFFF).
Note that if a negative value is output, the low-order word information will be output
after being converted to hexadecimal.
Examples: A%=SOW(2)
→The output status of SOW (2) is
assigned to variable A%.
SOW(15)=A%
→The contents of variable A% are
assigned in SOW (15).
If the variable A% value exceeds the output range,
the low-order word information will be assigned.
SOW(15)=-255
→The contents of -255 (&HFFFFFF01) are
assigned to SOW (15).
-255 is a negative value, so the low-order
word information (&HFF01) will be assigned.
• The information is handled as unsigned word data.
• If a serial port does not actually exist, the data is not output externally.
• If a value exceeding the output range is assigned, the low-order 2-byte information is output.
9.13 Serial double word output
Output the status of serial output word information in a double word, or indicates the output status.
Format
SOD(m)
Values m : port number .................... 2, 4, 6, 8, 10, 12, 14
The output range is -2,147,483,648(&H80000000) to 2,147,483,647(&H7FFFFFFF).
Examples: A%=SOD(2)
→The output status of SOD (2) is assigned to variable A%.
SOD(14)=A%
→The contents of variable A% are assigned in SOD (14).
• The information is handled as signed double word data.
• If a serial port does not actually exist, the data is not output externally.
• The lower port number data is placed at the lower address.
For example, if SOW(2) =&H2345, SOW(3) =&H0001, then SOD(2) =&H00012345.
