■ Number of bits (Bit 10) [Initial setting: 16 bits]
Specify the number of bits to be used to display the numeric value.
• To display a value with 32 bits, turn on Bit 10.
• The 32-bit display is available only for devices TM and DM.
• When 32-bit display is set, the specified device is displayed in low-order bits,
and the device that has the next device number of the specified device is
displayed in high-order bits.
• Devices CTC and CTH can be displayed with 24 bits, which is specified with the
MEMSW instruction. (In this case, the Bit 10 setting is ignored.)
■ Notation (Bit 11) [Initial setting: Decimal]
Specify the notation used for the numeric value to be displayed.
• To select hexadecimal notation, turn on Bit 11.
• In the hexadecimal notation, "$" is prefixed to the numeric value and the zero-
suppression function is disabled.
• If a device has a preset value such as timers and counters, the same notation is
used for both the preset value and the current value.
• The initial setting for relay is turning on/off one bit. When Bit 11 is ON, the
status of eight bits is displayed collectively. These eight bits cannot be turned
on or off.
• When eight bits are displayed collectively, relays of eight bits starting from the
specified relay are displayed.
Example
When relay 00502 is specified, the status of relays 00502 through 00509 is
displayed from the right end.
■ Show/hide preset values (Bit 12) [Initial setting: Show preset values]
Specify whether or not to display a preset value when the device has a preset
value such as timers and counters.
• To hide the preset value, turn on Bit 12.
■ Zero-suppression setting (Bit 13) [Initial setting: Use zero suppression]
Specify whether or not to use the zero-suppression function for the displayed
preset value.
• To disable the zero-suppression function, turn on Bit 13.
■ Enable/disable changing preset values (Bit 14) [Initial setting: Enable]
If a device has a preset value such as timers and counters, specify whether or not
to change the preset value with the KV-D20.
• To disable changes, turn on Bit 14.
■ Enable/disable changing (current) values (Bit 15) [Initial setting: Enable]
Specify whether or not to change the currently displayed value with the KV-D20.
• To disable changes, turn on Bit 15.
