Yes
The PGC sends answer data and fulls unassigned Modbus registers with "0" (ze-
ro). In this case, a signal query of the ERZ2000-NG is adequate.
IL55 Byteorder 16-Bit Int
The byte sequence of 16-bit integers can be adjusted here. A 16-bit value con-
sists of two bytes, the lower-significance byte and the higher-significance byte.
The following setting options are available:
Æ 12 / 21
IL56 Byte ord 32-Bit-Int
The byte sequence of 32-bit integers can be adjusted here. A 32-bit value con-
sists of four bytes. The following setting options are available:
Æ Æ 1234 / 2143 / 3412 / 4321
IL57 Byte order float
The byte sequence of single exact floating point numbers can be adjusted here.
A single exact floating point number consists of four bytes. The following setting
options are available:
Æ 1234 / 2143 / 3412 / 4321
IL58 Byte order double
The byte sequence of double exact floating point numbers can be adjusted
here. A double exact floating point number consists of eight bytes. The following
setting options are available:
Æ 12345678 / 21436587 / 34127856 / 43218765 / 56781234 / 65872143 / 78563412
/ 87654321
The following applies for coordinates IL55 to IL58:
The numbers symbolize the significance. The significance of the byte increases
with the numerical value. The sequence is read from left to right.
IL70 Currently selected
Shows the currently active Modbus master and thus the assigned PGC.
IL71 Contact position
Shows the current switching status of the selected control contact.
x
Off: Contact is switched off.
x
On: Contact is switched on.
IL72 Selection mode
This operating mode determines the manner in which the two Modbus masters work.
The following options are available:
x
Always Master 1
The ERZ2000-NG only works with a single PGC. Only Master 1 is active for query-
ing of gas analysis data of the assigned PGC 1.
