6. Procedure for Use
To Configure the Operating Period of the E018 Module
1. In the box E018 Period select the time which should be used between calls to the E018
module. The possible times are between 0.625 ms and 50 ms.
Select the
operating
period of
the E018
module
Configuring the Bus
The configuration of the input and output modules located in all the existing buses in each PLC
model should be declared in module C. In configuring the bus the input and output operands (% I and
% 0) are allocated to digital modules and indicated address of the address operands in the bus (%R).
In the box First Output Octet it is possible to define the operand address %S from when they are
reserved to the points of output. This value is automatically altered with the declaration of the I/O
modules in the buses, only needing to be modified for the user to reserve addresses %E for future
insertions of input modules.
The group Qualification keys for changing bus allows the qualification of the keys which control
the module changes with the PLC powered in bus 2 to 9 of the PLC. Each bus has a control key in
the power supply. If the key is to be enabled, (STBY), it has to stop its bus to change the modules. If
the key is disabled its bus always remains active, avoiding accidental shutdowns. In this last case,
however, the individual keys for controlling the modules present in the bus remain enabled, allowing
a change of modules which have this characteristic with the PLC powered.
To configure the bus of the series Quark, Piccolo e AL-600, AL-2000, AL-2003, AL-2004 and
AL-3000:
1. Select the button Bus. The dialogue box Bus for configuring the buses is shown.
2. In the box First Output Octet, key in the number of the first output octet, if a different
value is required from that which is automatically configured, being the address of the
last but one input.
3. In the verification box Change of Modules with Powered PLC, the item should be
selected in case a change of modules with a powered PLC is being used. This item only
exists in CPUs AL-2002/MSP and AL-2003.
4. In the panel Equalification keys for change bus select the buses which should have
their key enabled.
