3.2.10 Fault memory
The fault memory can be activated or deactivated with the parameter "M" in
the menu "out". When the fault memory is activated, all pending LED and
alarm messages remain available until they are deleted by using the reset but-
ton (internal) or if the supply voltage U
s
is turned off.
3.2.11 History memory HiS
When the first error occurs after clearing the history memory, all measured
values (that are marked in the table in Chapter 5.7) are saved in the history
memory. This data can be read out using the "HiS" menu item. In order to be
able to record a new data record, the history memory must first be cleared via
the menu using "Clr".
3.2.12 Interface/protocols
The ISOMETER® uses the serial hardware interface RS-485 with the following
protocols:
BMS
The BMS protocol is an essential component of the Bender measuring
device interface (BMS bus protocol). Data is transferred using ASCII
characters.
Modbus RTU
Modbus RTU is an application layer messaging protocol and it provides
Master/Slave communication between devices that are connected
together via bus systems and networks. Modbus RTU messages have a
16-bit CRC (Cyclic Redundant Checksum), which guarantees reliability.
