APC-OP-LIT 1/12
9.6 - Connection Object
Class ID 5
hex
Instance ID 1, 2 (1=EC, 2=IO)
• Attribute E &10: Setting of this
attribute is allowed only when in
configure I/O state.
• Attempt to set unsupported
EPATH returns an “invalid
attribute value” error.
• The current assembly path is
stored in the device’s NVRAM
and restored on power up.
• Watch dog timeout action:
0 = transition to timeout,
1 = auto delete.
• Attribute 7 and 8: report 12 for
explicit connection or the actual
static assembly length in IO.
