3-3 Explicit Messaging

3-33

Communicating with the SK-1000 Series

- DeviceNet Compatible Network Unit DL-DN1 User’s Manual (SK-1000) -

*7 This is 999.8 when the humidity is not acquired correctly.

*8 If a prohibited combination of functions is written, it results in "abnormal setting

(1)." For details of each function, refer to the SK-1000 Series User's Manual.

*9 The "initial reset request" motion command result is included in this item.

Regarding data category N x 10 + 1 Data No. 79 (EEPROM writing result), a "0:

writing in progress" status is maintained for 2 seconds after completion of the

final write command transmission to the nonvolatile memory (EEPROM). Writing

begins 2 seconds later, and if completed normally, the result is "1: successfully

completed".

[Example] After every-second write command transmissions, a "0: writing in

progress" status is established for 2 seconds. A "0: writing in prog-

ress" status is maintained for 2 seconds after completion of the final

write command transmission, and writing then begins 2 seconds

later, with a result of "1: successfully completed".

However, writing begins immediately follow

ing a initial reset executed in

response t

o a data category N Data No. 69 "initial reset" request. A "1: success-

fully completed" result then occurs if all parameters have been saved to the non-

volatile memory (EEPROM) approximately 3 seconds later.

- 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 t

o 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 binary number gives "0110".

*12 This parameter works if "Bank switching method" is set to "button."

*13 These parameters are OFF only if data "0" is written and the wiring is configured

to turn off external input.

*14 A write control error results if data is rewritten to an expansion unit.
