6.12 Output Commands
(Measurement-RS-422/485
Dedicated Commands)
ESC O Opens the device
ESC is the character 1BH expressed using
ASCII code. See appendix 1.
Syntax ESC O p1
p1: Device address (01 to 32)
Example Open the device at address 01, and enable all
commands.
ESC O01
Description • Specifies the address of the device with which
to communicate.
• Only one device can be opened at any given
time.
• When the ESC O command is executed, any
other device that is currently open is
automatically closed.
• When this command is received correctly, the
CX transmits the data “ESC 0 ”.
• Normally, either CR+LF or LF can be used as
a terminator for communication commands.
However, the terminator for this command
must be set to CR+LF.
ESC C Closes the device
ESC is the character 1BH expressed using
ASCII code. See appendix 1.
Syntax ESC C p1
p1: Device address (01 to 32)
Example Close the device whose address is 01.
ESC C01
Description • Clears the current connection with the
connection.
• When this command is received correctly, the
CX transmits the data “ESC C ”.
• Normally, either CR+LF or LF can be used as
a terminator for communication commands.
However, the terminator for this command
must be set to CR+LF.

6.13 Output Commands
(Control)
FP Outputs the SP number and PID
number.
Syntax FP p1
p1: Loop number (1 to 6 (1or 2 on the CX1000))
Query FP?
Example Output the SP number and PID number of loop
number 2.
FP2
Description Outputs the SP number and PID number that is
currently used by the selected loop.
FM Outputs the control mode.
Syntax FM p1
p1: Loop number (1 to 6 (1or 2 on the CX1000))
Query FM?
Example Output the control mode of loop number 2.
FM2
Description Outputs the status of the control mode of the
selected loop. The status is indicated using 32
bits that are divided into 4 groups of 8 bits.
xxx.xxx.xxx.xxx
For details, see “Control Mode Output” in section
7.2, “ASCII Data Output Format.”
FH Outputs the program operation
mode.
Syntax FH p1
p1: Program parameter numbers (1–30)
1–30: pattern number 1 to pattern number
30
When omitted, assumes the pattern
numbers designated on the CX.
Example Outputs the status of pattern number 2’s
program operation mode
FH2
Description The status of the operation mode of the selected
pattern is output. The status is indicated using
32 bits that are divided into 4 groups of 8 bits.
xxx.xxx.xxx.xxx
For details, see “Program Operation Mode
Output” in section 7.2, “ASCII Data Output
Format.”
