IGWiPS200-1
INTRODUCTION
This publication describes installation of the Siemens Wireless
Process Solution (WiPS) 200 Series Two-Way Multipoint-To-Point
Radios and I/O Expansion Modules. Radios (i.e. transceivers)
1 and
I/O modules are used to construct a WiPS wireless network for the
gathering and distribution of process related analog, digital, and
pulse/frequency data. Table 1, on the next page, identifies each
WiPS 200 Series model. The table also provides a description of
each item and an order/part number. Shown at right are a
transceiver, the right-most module, and five I/O modules mounted
on a section of DIN rail.
A WiPS wireless network is built using a selection of transceivers,
I/O Expansion modules, and accessories, such as antennas, antenna
cables, and power supplies. Transceivers perform two-way wireless
communications. They also have I/O capability with one analog
input channel, one analog output channel, two digital input channels, and two digital output channels. I/O Expansion
modules perform the bulk of the process data gathering and distribution. A selection of modules is available to
accommodate analog, digital, and pulse/frequency data. Antenna selections include a wide range of omnidirectional
and Yagi directional models. These antennas can be paired with low loss antenna cable to further improve
transmitted signal strength allowing communication over longer distances. Siemens Logo power supplies are
available to power transceivers and I/O Expansion modules. Other accessories include surge voltage protection
adapters and cable connector adapters.

Two types of transceivers are provided: Master and Remote (i.e. Slave
2 ). The master transceiver is installed at a
central data collection and processing location, such as a control room. Remote transceivers are installed near field
devices, such as transmitters, counters, motors, fans, conveyer belts, stirrers, and annunciators. Each wireless
network must have one master transceiver and at least one remote transceiver. Up to eight remote transceivers can
be installed on a network allowing access to widely distributed field devices.
Table 1 lists the seven types of WiPS I/O Expansion modules and their model and order numbers. I/O Expansion
modules are added to the wireless network’s Master and Remote transceivers in complementary pairs. Up to eight
I/O Expansion modules of any combination can be connected to a Master transceiver. Eight complementary I/O
Expansion modules can then be connected to up to eight remote transceivers. Thus a total of sixteen modules can be
connected to your WiPS wireless network. As mentioned above, I/O Expansion modules are added to the network in
complementary pairs:
• An input module at the Master transceiver must be complemented by an output module of the same type at a
remote transceiver.
• An output module at the Master transceiver must be complemented by an input module of the same type at a
remote transceiver.
The network can accommodate a maximum of 32 analog signals or 64 digital signals or 16 pulse signals or a
combination of analog, digital, and pulse signals (total of inputs or outputs, not the sum of input and outputs).
