BCD Separate the byte in two nibbles, and reads them as decimal
(from 0 to 9)
Example:
23 → 17 (in decimal format)
0001 0111 =23
0001 = 1(first nibble)
0111= 7 (second nibble)
Select the conversion and click on plus button. The selected item will be added on
Configured list.
If more conversions are configured, they will be applied in order (from top to bottom of
Configured list).
Use the arrow buttons to order the configured conversions.
Retentive Memory variables
System Variables - RetentiveMemory protocol allows to create Tags that point to a memory area whose content is
maintained when HMI is powered off.
The physical support for retentive memory is based on FRAM technology.
Important: Not all HMI devices include FRAM memory. If FRAM memory is not available, persistency
is supported using user memory storage (Flash or hard disk drive). Flash technology has a limitation
in the maximum number of write operations. The use of Flash as storage media for retentive memory
with frequent write operations may damage the memory components. Check HMI device data for
availability of FRAM memory.
Important: Retentive memory is 16 KB flat memory area organized in bytes and accessible through an
offset. Refer to schema below.
