| Note MANA on terminals 19 and 20 is equivalentThis section contains the block diagram of the digital on-board I/O (X11) with standard inputs |
|
| nd outputs and the encoder supply, as well as the rules for the correct wiring of the ground connections. |
|
| For information on wiring the front connector, establishing the cable shield, etc., refer to the , ET 200MPThe digital on-board I/O is supplied via the front connector terminals and therefore does not |
require power to be supplied by the infeed element. The infeed element is, however,
necessary for shielding.
Output driver
The digital onboard I/O uses the following output drivers:
● X11, DQ0 to DQ7: Push-pull stage and freewheeling diode
● X11, DQ8 to DQ15: High-side switch and freewheeling diodeAn internal protective circuit protects the digital on-board I/O against destruction if the
polarity of the supply voltage is reversed. In the case of polarity reversal of the supply
voltage, however, unexpected states can occur at the digital outputs.The inputs and outputs of the digital on-board I/O are divided into two load groups which are
supplied with 24 V DC.
The digital inputs DI0 to DI15 form a load group and are supplied via the connections 1L+
(terminal 19) and 1M (terminal 20).
The digital outputs DQ0 to DQ7 are supplied via the connection 2L+ (terminal 29). The digital
outputs DQ8 to DQ15 are supplied via the connection 3L+ (terminal 39). Please note that the
digital outputs DQ0 to DQ15 only have a common ground. In each case, they are led through
to the two terminals 30 and 40 (2M/3M) and bridged in the module. The digital outputs form a
common load group.The ground is supplied with a first cable from the central terminal block to terminal 30 of the
module and additionally with a second cable also from the central terminal block to
terminal 40 of the module.
At the digital outputs, each of the ground connections of the loads is connected with a
separate cable for each load to the central terminal block.
Response of the digital outputs to a wire break at ground connection of the outputs
Due to the characteristics of the output driver used in the module, approx. 25 mA supply
current flows out through the outputs via a parasitic diode in the event of a ground wire
break. This behavior can lead to non-set outputs also carrying high levels and emitting up to
25 mA output current. Depending on the type of load, 25 mA can be sufficient to control the
load with high level. To prevent unintended switching of the digital outputs in the event of a
ground wire break, follow these steps:
Wire to ground twice
Connect ground to terminal 30 and to terminal 40.
1. Route the first ground connection from terminal 30 to the central ground connection of the
plant.
2. Route the second ground connection from terminal 40 to the central ground connection of
the plant.
If terminal 30 or 40 are interrupted by a ground wire break, the outputs will continue to be
supplied via the second, intact ground connection.
