Communicating with the GT2 series

*1 The error content of the sensor amplifier can be checked by noting the ON/OFF

state of each bit.

OFF (0): No error; ON (1): Error

More than one error may occur simultaneously. For details of each error, refer to

the GT2 Series User's Manual.

*2 Details of output status can be checked by noting the ON/OFF state of each bit.

*3 If the judgment value is correct, the parameter range is - 199.9999 to 199.9999.

When the cur

rent value is ove

r range, "999.9999" is stored.

When the current value is under range, "- 999.9999" is stored.

When the current value is invalid, "- 999.9998" is stored.

When an error occurs, "1000.0000" is stored.

*4 When you use the calculation function and calculation setting is set to other than

standard difference display, a reading error occurs on the expansio

n unit.

*5 In the calculation-only mode, a reading error occurs on the ma in unit.

*6 This parameter can be used only when the detection mode of the sensor ampli-

fier is pea k-to-peak hold. A reading error occurs when the mode is set to other

than peak-to-peak hold.

This parameter may be used for judging the outer diameter of cylinders, in order

to read the peak and bottom values du ring measurement.

*7 When you do not use the calculation function, a reading error occurs.

When the calculation setting is set to other than standard difference display, a

reading error occu rs on the expansion unit.

When the calculation setting is set to difference display, a reading error occurs

on the main unit.

*8 These parameters cannot be read/written when a sensor amplifier of GT2-

71MC* series is used.

*9 This parameter cannot be written to expa nsion units if the key lock function is

used by the main unit when simultaneous input is active. When a sensor ampli-

fier of GT2-100* series is us ed, this parameter cannot be written to units other

than the main unit (ID: 01).

*10 This parameter cannot b e written when the key lock function is used.

*11 When a sensor amplifier of GT2-100* series is used, this parameter cannot be

written to units other than the main unit (ID: 01).

*12 These parameters can be read/written to only the main unit (ID: 01) of sensor

amplifiers.

*13 Each parameter is speci

fied as a combination of calculation mode and calcula-

tion setting. The calculation mode is defined in the tens digit, while the calcu la-

tion setting is defined in the ones digit.

If calculation is not available (00 + m): Specify 0 in the tens digit, and specify the

desired number (0 - 7) in the ones digit, so that: the result is between 00 (0h)

and 07 (7h). The specified calculating se

tting is written to the sensor amplifier,

but it is invalid.

If calculation mode is ava ilable (10 + m) for torsion (5): 15 (Fh).

If calculation-only mode is available (20 + m) for mean (3): 23 (17h).

*14 Available only for GT2-100 series. Not available for GT2-70 series.

This parameter can be read/written only when GT2-100* is used as a main unit
