Bit

Description

DYC03

B08

Power Start-up Reset Command
= 0 Normal
= 1 Reset Power Start-up Bit
A false-to-true transition of this bit forces the module to unlatch SYS01-B08.

B09

Alarm Reset Command
= 0 Normal
= 1 Reset Latched Alarms
A false-to-true transition of this bit forces the module to unlatch all bits in SYS09, SYS10, SYS11, and SYS12.

B10

Profile Status Bits Reset Command
= 0 Normal
= 1 Reset Profile Status Bits
A false-to-true transition of this bit forces the module to unlatch the 15

profile complete status bits, SYS02-B00 -

SYS02-B14 inclusive.

B11-
B14

Open

B15

Continue Ejector Profile command
= 0 Normal
= 1 Continue Ejector Profile
A false-to-true transition of this bit forces the module to resume the Ejector Profile from the stop-and-notify pause.
The module completes the next programmed Ejector Profile stroke unless interrupted by any

one of:

– any other action execution command
(commands to start any Clamp Close Profile will be ignored)
(commands to start any Clamp Open Profile will not interrupt)

– the dynamic stop command (DYC02-B15 = 1), or

– a clamp position equal to or less than EPC62

if:

then the module:

– SYS21-B14 = 0, or SYS03-B08 = 0, or

ignores this bit

– EPC03-B09 = 1, or EPC03-B12 = 0, or
– clamp position is equal to or less than EPC62

– the module receives this bit when EPC03-B09 = 0

sets alarm status bit SYS14-B09

and clamp position equals or is less than EPC62

DYC04

Status Request Commands

Bits DYC04-B00 - DYC04-B07 are the eight command bits available to request the Status Blocks that the module re-
turns with the next BTR to the PLC processor. The module does

not respond to any bit associated with an unsupported

status block (based on Module I/O configuration). The module defaults to returning System Status Block (SYS) if none
of these eight bits are set or if the last BTW received at the module was not the Dynamic Command Block (DYC). If
more than one of these eight bits are set, the module prioritizes BTR service by responding to the lowest-numbered bit.

B00

= 0 Normal
= 1 Return CPS with next BTR

B01

= 0 Normal
= 1 Return IPS with next BTR

B02

= 0 Normal
= 1 Return HPS with next BTR

B03

= 0 Normal
= 1 Return PPS with next BTR

B04

= 0 Normal
= 1 Return OPS with next BTR

B05

= 0 Normal
= 1 Return EPS with next BTR

B06

= 0 Normal
= 1 Return RLS with next BTR

B07

= 0 Normal
= 1 Return CLS with next BTR
