Communicating with the IL Series
- When "zero shift status save" is ON, writing begins immediately for data cat-
egory N Data No. 65 "zero shift request" and Data No. 66 "zero shift reset
request".
*10 The command reads the execution result of the "zero shift request" or "zero shift
reset request" whichever was last issued.
*11 By reading the "system parameter current state," the system parameters of the
sensor amplifier can be checked. The system parameters are comprised of the
settings of "judgment output/check output" polarity and analog output.
The "system parameter" attribute specifies the system parameters which are set
when the "system parameter set request" is executed by a motion command.
The values to be read or written are specified by translating them to binaries and
using ON or OFF in each bit of the binaries.
Assume the read data is "006":
Translating "6" to a bina
ry number gives
"0110".
*12 This command reads the execution result of the "Tolerance tuning request",
"Two-point tuning HIGH side 2nd point confirmation", "Two-point tuning LOW
side 2nd point confirmation", "One-point tuning request for diff. count filter", or
"Two-point tuning 2nd point confirmation for diff. count filter" motion command
whichever was last issued.
*13 This parameter works if "Bank switching method" is set to "button."
*14 These parameters are OFF only if data "0" is written and the wiring is configured
to turn off external input.
*15 When using the IL-300/IL-600, 0 to +999.99, and when using the IL-2000, 0 to
+9999.9.
*16 A write control error results if data is rewritten to an expansion unit.
*17 In order to apply the settings of data category N x 10 +4 Data Nos. 76 to 79 to
the sensor amplifier, either Data No. 75 must be set to "1 (user setting)", or the
sensor amplifier operation buttons must be used
t
o specify the "external input"
setting as "user setting".
*18 An ASCII character string is sent back in response data (4 bytes). The data
types is DINT.
For "IL-1", the response is "494C2D31h".
