5-128 F650 DIGITAL BAY CONTROLLER GEK-106310-AF
5.5 CONTROL ELEMENTS CHAPTER 5: SETPOINTS
DigCnt X Function: This setting allow to Enables or disables the specified counter. If a counter’s DigCnt X
Function is set to Disabled, then the DIGCNT X HI, DIGCNT X EQ and DIGCNT X LO are
set to OFF and the DIGCNT X VALUE, DIGCNT X FROZENVALUE and DIGCNT X
FROZENDATE are set unaltered.
DigCnt X Name: Sets a name to identify the specified counter. Note that the name length is cut down to
only 12 characters long.
DigCnt X Preset: Indicates the preset value that the specified counter can be set before counting
operations begin or after a reset command is accomplished.
DigCnt X Compare: Indicates the comparison value that the specified counter current value is compared
to and several logic bits (HI, EQ and LO) are updated accordingly.
Snapshot Events: This is a global setting that affects all of 8 digital counters. Enables or disables the
snapshot events for this function. Note that all enabled digital counters are affected by
this setting.
Relat configuration
To the correct operation of each counter, there are several PLC status variables in Enervista 650 Setup at Setpoint> Relay
Configuration>Control Elements section that should be configured properly. Each one of the 8 digital counters has its
own PLC statuses and they are identical:
DIGCNT X BLOCK: Blocks the functionality of the specified counter. If a counter’s DIGCNT X BLOCK is set to 1, all the
counter’s values remain unaltered and no counter commands are processed. When the
counter’s DigCnt X Function is set to Enabled and the DIGCNT X BLOCK is set to 0, then the
counter starts running and accepting counter commands.
DIGCNT X UP: Counter command. When this element changes from 0 to 1, the value of the specified counter is
incremented by 1. If the current counter value is 2,147,483,647 and is incremented, the updated
value is set to -2,147,483,648.
DIGCNT X DOWN: Counter command. When this element changes from 0 to 1, the value of the specified counter is
decremented by 1. If the current counter value is -2,147,483,648 and is decremented, the
updated value is set to 2,147,483,647.
DIGCNT X SETPRESET: Counter command. This element defines the behavior of the specified counter’s Reset and the
Freeze/Reset commands or when counter is set from Disabled to Enabled:
• If set to 0, all commands with a Reset involved or when counter is Enabled set the initial counter value to 0
• If set to 1, all commands with a Reset involved or when count
er is Enabled set the initial counter value to the one
specified in the setting DigCnt # Preset.
