1- If the value in the monitored target register is not a valid BCD number, a dollar sign ‘$’ is
displayed.
2- Floating Point format is based upon the IEEE 754 standard for 32-bit single precision
numbers. A maximum of nine digits is supported. Values are rounded to the nearest decimal
point (ex: if Format: Digits after Decimal Point is set to 1 digit, then floating point number
1.52 would be displayed as 1.5 and 1.56 would be displayed as 1.6).
3- ASCII format interprets the data value in each 16-bit register as two ASCII printable
characters. Hex values 0-9 are displayed as numbers 0-9, 0A-1F is displayed as small case
decimal numbers, 20-FF is printable ASCII characters. The HMC reads consecutive registers
according to the Length field (ex: if Length=10, then HMC will read five consecutive registers,
starting with the designated Tag Address).
4- ASCII Numeric is the same as ASCII except that all non-printable values are displayed as
zeroes.
o Enable Control Bit – if enabled, the HMC monitors the selected bit tag address.
‘0’ prevents a new entry, ‘1’ allows normal editing by the operator.
o Hide Data – if enabled, data will be represented with asterisks ‘***’. This
feature used for security password entry.
o Keypad (List Pd) – selects using a popup keypad (Yes) or use a keypad on located
on the same screen (No)
o Maximum/Minimum Value (List Pe) – select the limits that the operator enters
as a valid number
o Screen Name/Number (List Pd) – determines which popup keypad to use
o Tag Address (List Qa) – this is the address of target register that is monitored
o Tag Name (List Qb) – this is the name given to the tagged register in the Tag
Database.
Design (List S) – identifies object
Layout (List T) – coordinates (i.e. size and position) for the object
Operation – use this feature to perform a mathematical calculation on the object data.
o First Operation – this is the first mathematical operation performed on the data
object. Options are NOP (no operation), addition (+), subtraction (-),
multiplication (*), and division (/).
