DYC
The module will not accept or process the Dynamic Command
Block unless it has a valid MCC installed.

Description
DYC01
Block ID = 00011001 (low byte)
Action Execution Commands in high byte
Bits DYC01-B08 - DYC01-B15 and all 16 bits in DYC02 are the 24
action execution commands to control the module.
Because the module cannot respond to more than one action execution command at a time (exception: it can start a
Clamp Open Profile and Ejector Profile concurrently), the module ceases all action execution and sets its outputs to
zero when it decodes a valid dynamic command block with more than one of these bits SET. The module senses this
invalid request and latches alarm status bit SYS14-B00, and unlatches SYS14-B00 when it decodes a valid Dynamic
Command Block with one or none of the action execution bits SET.
B08
Set-output Command
= 0 Normal
= 1 Execute Set-output
When the module decodes a valid DYC having this bit SET, it sets its outputs to DYC09 - DYC16. The outputs remain
at these values as long as this bit is SET, and return to zero when this bit is RESET.
Jog Commands
B09
= 0 Normal
= 1 Execute Screw Rotate Jog
When the module decodes a valid DYC having this bit SET, it sets its outputs to JGC09 - JGC16. The outputs remain
at these values as long as this bit is SET, and return to zero when this bit is RESET.
B10
= 0 Normal
= 1 Execute Ram (Screw) Forward Jog
When the module decodes a valid DYC having this bit SET, it set its outputs to JGC17 - JGC24. The outputs remain at
these values as long as this bit is SET, and return to zero when this bit is RESET.
B11
= 0 Normal
= 1 Execute Ram (Screw) Reverse Jog
When the module decodes a valid DYC having this bit SET, it sets its outputs to JGC25 - JGC32. The outputs remain
at these values as long as this bit is SET, and return to zero when this bit is RESET.
B12
= 0 Normal
= 1 Execute Clamp Forward Jog
When the module decodes a valid DYC having this bit SET, it sets its outputs to JGC33 - JGC40. The outputs remain
at these values as long as this bit is SET, and return to zero when this bit is RESET.
B13
= 0 Normal
= 1 Execute Clamp Reverse Jog
When the module decodes a valid DYC having this bit SET, it sets its outputs to JGC41 - JGC48. The outputs remain
at these values as long as this bit is SET, and return to zero when this bit is RESET.
B14
= 0 Normal
= 1 Execute Ejector Advance Jog
When the module decodes a valid DYC having this bit SET, it sets its outputs to JGC49 - JGC56. The outputs remain
at these values as long as this bit is SET, and return to zero when this bit is RESET.
B15
= 0 Normal
= 1 Execute Ejector Retract Jog
When the module decodes a valid DYC having this bit SET, it sets its outputs to JGC57 - JGC64. The outputs remain
at these values as long as this bit is SET, and return to zero when this bit is RESET.
DYC02
Action Execution Commands
Bits DYC01-B08 - DYC01-B15 and all 16 bits in DYC02 are the 24
action execution commands to control the module.
Because the module cannot respond to more than one action execution command at a time (exception: the module can
start a Clamp Open Profile and Ejector Profile concurrently), the module ceases all action execution and sets its out-
puts to zero when it decodes a valid Dynamic Command Block with more than one of these SET. The module senses
this invalid request and latches alarm status bit SYS14-B00, and unlatches SYS14-B00 when it decodes a valid Dy-
namic Command Block having one or none of the action execution bits SET.
