3.4.9.3 LOGIC I/O Interface
The LOGIC I/O Interface provides connections between the Controller Module and the customer's PLC. Trigger input,
ready out and fault out signals are communicated to and from the PLC. Refer to Tables 3.4 and 3.5 for signal
descriptions.
Signal Functions
Isolated Inputs 1 - 4 -
The Isolated Inputs 1
– 4 provide four configurable input signals (Input 1, Input 2, Input 3 and
input 4) configurable in the Setup B screen (see 3.3.7.7). The four inputs can be configured as Disabled or a Trigger,
Lock or Link input.
Isolated Outputs 1 - 4 -
The Isolated Outputs 1
– 4 provide four configurable output signals (Output 1, Output 2,
Output 3 and Output 4) configurable in the Setup B screen (see 3.3.7.7). The four outputs can be configured as
Disabled or a Busy, Ready, Status, Success or Link output.
Recipe In Bits 0
– 4, Recipe In Bit Strobe and Recipe In Bit Common -
The Recipe In Signals provide the ability to
change the present recipe of the controller. The Recipe In Bits should be configured to the desired recipe number and
then the Recipe In Bit Strobe should be set true to latch in the recipe. To select recipe 32 all bits should be false and
then set true the Recipe In Bit Strobe. It is not possible to select recipe 0. All Recipe In Bits are optically isolated from
the internal control electronics. The Recipe In Bits and Recipe In Bit Strobe share the Recipe Out Bit Common.
Recipe Out Bits 0
– 4, Recipe Out Bit Strobe and Recipe Out Bit Common -
The Recipe Out Signals provide the
ability to monitor the present recipe of the controller. The recipe bits only indicate a valid recipe when the Recipe Out
Bit Strobe is true. When the present recipe is 32 all Recipe Out Bits will be false and the Recipe Out Bit Strobe
will be true. When the present recipe is 0 all Recipe Out Bits will be false and the Recipe Out Bit Strobe will be true.
The Recipe Out Bits and Recipe Out Bit Strobe share the Recipe Out Bit Common.
Signal Levels
All signals are
optically isolated. The power for all signals is provided by the customer’s equipment.
All inputs accept a 24 VDC signal and require 20 mA.
The conduction level of each output is configurable in the Setup E screen. By default, Output 2 is configured as a
<STATUS> FAULT signal with the conduction level set to not conducting when 'true'. While this may be reconfigured,
using this configuration allows a broken connection in this signal path to appear as a FAULT condition to the
monitoring equipment.. Outputs can switch a signal of up to 24 VDC and 20mA.
For further description of the input and output electrical characteristics and wiring please see Technical Bulletin 134
(TB-134).
Connections
All connections are through a 37-pin circular plastic connector, with the mating connector (AMP # 206150-1),
backshell (AMP # 206138-1), pins (AMP # 66105-4), and key (AMP # 200821-1) supplied with the unit. Table 3.6
shows the connector pin layout.
