12.2 Software: Error Codes
The following table lists error codes that are encountered when attempting to make an invalid connection between blocks
on the
Functional View
tab.
Software Code Error
A.1
This connection creates a loop.
A.2
A connection from this block already exists.
A.3
Connecting a block to itself is not allowed.
B.2
This Bypass Block is connected to a Two-Hand Control Block. You can connect only a Two-Hand Control input to the
IN
node.
B.3
This Bypass Block is already connected to another block.
B.4
This Bypass Block is connected to the
TC
node of a Two-Hand Control Block and cannot be connected to any other blocks.
B.5
Cannot connect Two-Hand Control Input to the
IN
node of this Bypass Block because it has the "Output turns Off when both inputs (IN
and BP) are On" option disabled.
B.6
The IN node of a Bypass Block cannot be connected to Emergency Stop and Rope Pull inputs.
B.7
The IN node of a Bypass Block cannot be connected to Emergency Stop and Rope Pull inputs via other blocks.
C.1
Only a Cancel Off Delay input can be connected to the
CD
node.
C.2
A Cancel Off Delay input can be connected only to the
CD
node of a Safety Output.
D.1
This External Device Monitoring input is configured for a Dual-Channel 2 Terminal circuit and can be connected only to the
EDM
node of a Safety Output.
E1
The Enabling Device Block output nodes (
P
or
S
) can be connected only to the
IN
node of a Safety Output.
E.2
The
IN
node of an Enabling Device Block cannot be connected to Emergency Stop and Rope Pull inputs.
E.3
The
ED
node of an Enabling Device Block can be connected only to an Enabling Device input.
E.4
The
ED
node of an Enabling Device Block cannot be connected to Emergency Stop and Rope Pull inputs via other blocks.
E.5
An Enabling Device Block that has a Two-Hand Control input connected to the
IN
node cannot be connected to a Safety Output that
has
Safety Output Delay
set to "Off Delay".
E.6
The secondary output node
S
of an Enabling Device Block can be connected only to the
IN
node of a Safety Output.
F.1
Emergency Stop and Rope Pull inputs cannot be muted.
F.2
Emergency Stop and Rope Pull inputs cannot be connected to a Latch Reset Block that is connected to a Muting Block.
F.3
A Latch Reset Block that is connected to an Emergency Stop or a Rope Pull input cannot be connected to a Muting Block.
G.1
Only a Manual Reset input can be connected to the
FR
node of a Safety Output.
G.2
Only a Manual Reset input can be connected to the
LR
node of a Latch Reset Block or Safety Output.
G.3
Only a Manual Reset input can be connected to the
RST
node of an Enabling Device Block.
G.4
A Manual Reset input can be connected only to
LR
and
FR
nodes of a Safety Output, an
LR
node of a Latch Reset Block, an
RST
node of an Enabling Device Block, and
SET
and
RST
nodes of the Flip-Flop Blocks.
H.1
A latch reset block already connected to a function block cannot connect to a Mute block.
H.2
A latch reset block already connected to a Mute block cannot connect to another function block.
I.1
Only Muting Sensor Pair, Optical Sensor, Gate Switch, Safety Mat, or Protective Stop inputs can be connected to the
MP1
and
MP2
nodes of a Muting Block or to the
MP1
node of a Two-Hand Control Block.
I.2
The
MP1
and
MP2
nodes of a Muting Block and the
MP1
node of a Two-Hand Control Block can be connected to inputs that are using
only Dual-Channel circuits.
I.3
A Muting Sensor Pair input can be connected only to
MP1
and
MP2
nodes of a Muting Block or the
MP1
node of a Two-Hand Control
Block.
