22 Configuration - Interface
Addr. ext.
binary value A maximum of 54 external binary tracks (binary values) can be read into the
paperless recorder. The following parameters must be configured for each
binary variable.
Addr. ext. text A maximum of 27 texts can be read into the paperless recorder.
Data format Selection of the format in which data are to be received.
For the float format, you can define whether the LSB
(least significant bit) or MSB (most significant bit) is
transmitted first.
In the unsigned integer format (UInt: 0 — 65535) and the
integer format (Int: -32768 — 32767) you can define a
divisor for the division of the data that are received. The
purpose of the division is to make it possible for floating
point values to be transmitted in integer format. So the
sender must multiply the data by the corresponding
factor before transmission.
Device address The address of the slave device from which data
are to be fetched.
Modbus address Address within the instrument.
v See the instrument documentation for the slave device.
Bit number The bit (b0 — b15) that is to be read.
v See the instrument documentation for the slave device.
Bit quantity The number of bits to be read. The number “1” means
that one bit is read at every cyclical interval. If a number
larger than 1 is entered, then (commencing at the
Modbus address) several bits will be read and
automatically distributed to the following external binary
values. The entry template will be locked for subsequent
values.
Example: starting at "Ext. binary value 1“, 16 bits are
read. In the menu, the settings for “Ext. binary value 2“
to "Ext. binary value 16“ are locked. starting at "Ext.
binary value 17”, a new arrangement can be configured.
Device address The address of the slave device from which data
are to be fetched.
Modbus address Address within the instrument.
v See the instrument documentation for the slave
device.
Word number The read-in is always made as words, i. e. there will
always be at least two characters read.
