Safety considerations
The AIM module is a low voltage device. In a normal situation, it presents no safety risk
to the user.
When the AIM module is in use, it will contain a charge from 8V to
36V, depending on the current loop voltage used. Never disconnect
the AIM module from the rack with active power. When you remove
an AIM module that has been in use, always turn off the rack power
first.
In case of a severe train malfunction or wiring errors, there is a risk of
an electric shock through the bus cables.
The rack and modules can contain sharp edges. Use protective
clothing (gloves etc.).
The protection components on the module are intended to protect
module only from external surges and transients. They do not provide
protection against incorrect wiring or connection.
Correct handling of the module
Electrostatic discharge (ESD) can damage electronic circuits. EKE products are
protected against ESD. However, you run the risk of delivering electrostatic discharges
to the module whenever you handle it or any of its components.
To avoid this risk, only handle the AIM module at a static-free workstation. If this is not
possible, you must ground yourself using a wrist strap and a resistive connection cord.
Remember to handle the module according to these instructions even when you are
removing a defective module and sending it to maintenance.
Remember to handle the module according to these instructions even
when you are removing a defective module and sending it to
maintenance.
静电放电会损坏电子线路。保护EKE产品免受静电放电。无论怎样，每当你处理模块或其任何组件时，都会有向模块发送静电的风
险。
为了避免这种风险，可以在防静电工作台上处理模块。如果还不能奏效，你必须带手环和接地线进行连接。即使在拿出有缺陷的模块
进行维护时也要按照这个指令操作。

2.4.4Module temperature and self tests
The module has a sensor that measures the temperature of the module continually
with 3 ºC (Celsius) accuracy, and informs the Coach Computer CPU about it.
When the module is installed in a rack and the power turned on, the module
performs memory tests on itself to make sure it is functioning correctly.

AIM Features and operation
AIM2505A Technical Manual V2.03 18
4. AIM Features and
operation
This chapter includes a brief description about the AIM firmware.
The following topics are covered in this chapter:
I/O-bus
Node address
Input channels
Other AIM module feature
I/O Bus
The AIM module is compatible with EKE-Trainnet® Common I/O-bus (later referred
to as I/O-bus). The I/O-bus is available in several EKE-Trainnet® Coach Computer
central processing units like CPU, CPG, CPR etc. In this document all these units
are referred to as CPU.
The following figure shows the principal connection between the AIM module and the
CPU.
Figure 4.1 AIM-CPU connection
On the CPU side, an I/O-bus master called CIAO manages all communication
between the AIM module and the CPU. The CIAO transfers all data coming from the
AIM module into Binary tree registers. An ISaGRAF application can read this data
from the Binary tree. In the same manner, if the ISaGRAF application wants to send
something to the AIM module, it writes the data to the Binary tree.
The CIAO transfers all data from the Binary tree registers to the AIM module. The
Binary tree register addresses and the contents of each register are explained in
Chapter 5: AIM Binary Tree.

AIM Features and operation
19 AIM2505A Technical Manual V2.03
Node addresses
There can be several I/O modules connected to one I/O-bus. To be able to separate
all I/O modules from each other, they must have a unique node address. A unique
node address is assigned to each I/O module depending on their slot position in a
rack. At power-up, every I/O module reads a physical address that is coded to the
rack backplane. Based on this physical address, the I/O module selects a node
address. Different rack type backplanes are coded differently. The I/O-bus node
address is thus dependent on both in what slot and in which rack type the module is
in.
4.2.1Rack types
Please refer to corresponding rack manual for information about
racks and IO bus slot addresses.

Frequency inputs (group 1)
AIMmodulehasfourfrequencyinputs that can be used for measuringinput frequency,
input pulse count and input pulse width ratio.
They can also be used as plain digital inputs.
Figure 4.2 Frequency input block
Additionally, inputs FREQ1 and FREQ2 (see table 4.5) can be paired to measure
phase direction between two signals of the same frequency that are phase shifted in
respect to each other. Another pair can be made from FREQ3 and FREQ4. This
enables applications such as measurement of train travel distance to be aware of
travel direction, which then can be used (with pulse counting) to estimate train
location on track.
Figure 4.3 Example of direction sensing capable tachometer
Frequency inputs have fixed positive going threshold level of 8V and negative going
threshold level of 7V. Input voltage range is specified up to 36V.
The GROUP1VSSI pins (refer to Table 4) on all channels are internally connected
together and therefore no voltage difference between GROUP1VSSI pins are
allowed.
