8.11. Save Calibration and Setup Data Commands
– CS, WP, SS, GI, PI
The calibration and setup parameters can be divided in 3 groups:
Calibration
: CM, DS, DP, CZ, CG, ZT, IZ and FD, etc. saved by command
CS
Setup
: FL, FM, NR, NT, BR, AD, DX and others, saved by command
WP
Setpoints:
S0, S1, H0, H1, A0, A1 saved by command
SS
Note:
Calibration data can only be saved if the TAC code is known and precedes the CS command. See the
CE
and
CS
commands in chapter 8.2.
The setup data and the setpoint data will be stored non-volatile in the EEPROM using the
WP
respective
SS
command.
8.11.1. CS Save the Calibration Data
[ SDO 2004 sub 02 ]
This command results in the calibration data being saved to the EEPROM and causes the TAC to be
incremented by 1.
Master (PC / SPS) sends
Slave (LDU 179.1) responds
Meaning
CE
E+00017 (example)
Request: TAC counter CE17
CE17
OK
Calibration sequence active
CS
OK
Calibration values saved
The CS command saves all of the calibration group values, as set by CZ, CG, CM‘n’, DS, DP and ZT. The
command returns ERR and has no updating action unless it is preceded by the CE_XXXXX.
8.11.2. WP Save the Setup Parameters
[ SDO 2004 sub 03 ]
With this
command the settings of the “Filter” (FL, FM), the “No-motion” (NR, NT) and the communication (AD,
BR, DX) will saved in the EEPROM.
Master (PC / SPS) sends
Slave (LDU 179.1) responds
Meaning
WP
OK
Setup data saved
WP
ERR
Error
8.11.3. SS Save Setpoint Parameters
[ SDO 2004 sub 05 ]
With this command the setpoints (S
’n’), the setpoint hysteresis (H’n’) and the setpoint allocation (A’n’) will be
saved in the EEPROM.
Master (PC / SPS) sends
Slave (LDU 179.1) responds
Meaning
SS
OK
Setpoint parameters saved
SS
ERR
Error
8.11.4. GI
Get an Image File from the EEPROM
[ n.a. ]
Retrieves a HEX-INTEL formatted EEPROM image file from the EEPROM of the source LDU. The image file
contains all stored information except the calibration data. This image file can be downloaded to any
LDU with the same firmware type and revision No. as the source LDU.
8.11.5. PI
Download an Image File to the EEPROM
[ n.a. ]
Downloads a HEX-INTEL formatted EEPROM image file to the target LDU EEPROM. The image file contains
all stored information except the calibration data.
Attention
: The target LDU must have same firmware type and revision no. as the source LDU.
