In addition, for devices with built-in motorized focus
Measuring distance XXXX in mm (is rounded up or down in 10 mm resolution!)
In addition, for devices with Profibus
Fieldbus address: 00..7fh
Fieldbus mode (00, 01, 02)
Mode 0 = old Profibus mode
(as formerly MS09 / MQ11, depending on the device)
Mode 1 = new M3 format (default, like fbx-codes)
Mode 2 = flexible format (see fbd codes)
Reset fieldbus (always apply if format change)
Fieldbus codes 32 bytes of data 32xYY (for mode 2)
Write fieldbus byte YY (address: XX = 00.1fh) (for mode 2)
Read fieldbus codes 32 bytes of data 32xYY (default for mode 1)
Old commands: to standardize the command structure, some old commands with numeric parameters are replaced with new
ones with hexadecimal coded. The old commands still work, but should no longer used in reprogramming:
ms (Read temperature value, 5-digit. dec.) mw
ez (Response time, 1-digit. dec.) et
lz (Max. value, 1-digit. dec.) lm in combination with lt
em (Emissivity, 2-digit. dec.) eg1
gt (Device temperature, 2-digit. dec.) ts
