Introduction
1.3 Symbols Used
This document contains symbols for the identification of warning messages and of informative
messages.
Warning Messages
You will find warning messages, whenever dangers may arise from your actions. It is mandatory
that you obser ve these warning messages for your personal safety and in order to avoid
property damage.
Depending on the risk level, the warning messages are displayed in descending order as
follows:
Danger!
This symbol indicates an imminent danger.
Non-observance will result in personal injury or death.
Warning!
This symbol indicates a possible fault or danger.
Non-observance may cause personal injury or serious property damage.
Caution!
This symbol indicates a possible fault.
Non-observance could interrupt the device and any connected systems and plants, or result in
their complete failure.
Informative Symbols
Note!
This symbol brings important information to your attention.
Action
This symbol indicates a paragraph with instructions. You are prom pted to perform an action or
a sequence of actions.

Product Description
2 Product Description
2.1 Use and Application
The WCS-PG 310 acts as an interface between the WCS reader and the PROFIBUS DP input
card of the control panel. The data is transferred between the WCS reader(s) and the WCSPG310 via the RS-485 interface, and from the WCS-PG310 to the control panel via the
PROFIBUS DP protocol.
You can connect up to four WCS readers of type LS221 or LS121. If you connect several
readers, they m ust have different addresses. The WCS-PG310 interface module constantly
queries the position values of the readers and always has the current reader data. The update
cycle for a reader is approximately 1 ms.
The WCS-PG310 interface module has the following configuration:
Baud rate: Max. 12 MBaud (automatic detection)
Diagnostic data: Max. 8 bytes
Sync: Supported
Freeze Supported
ID no.: 0x2079
2.2 Dimensions
The interface module housing has the following dimensions.

Product Description
Front panel
Figure 2.3 Front panel overview
Power:
The "Power" LED is green: The WCS-PG310 interface module is correctly connected to the
power supply.
State:
The "State" LED is green: Data is being exchanged with the WCS readers. The four
"ErrorNo/Select ID" LEDs are used to display the number of the currently polled reader.
ErrorNo/Select ID Reader address

Table 2.1 Display via the four "ErrorNo/Select ID" LEDs when the "State" LED lights up green
The "State" LED is red: The interface module has detected an error or a warning. The interface
module uses the "ErrorNo/Select ID" LEDs to display the binary coded error number or warning
number, and sends the num ber to the PROFIBUS master via the external diagnostic byte.
Error (no. 1...5): Switch the interface module off and back on. If the error occurs
again, the module must be replaced.
Warning (no. 6...15): The warning provides information. The interface module displays
the warning for one m inute and then resets automatically.

Rotary coding switches S4 and S5
The rotary switches S4 and S5 have no function. Ensure that the two switches are at position 0
to enable the data exchange mode.
Bus Power:
The "BusPower" LED is green: The LED is connected directly to the electrically isolated supply
voltage for the PROFIBUS side.
Bus:
The "Bus" LED is red: The interface module cannot exchange any data on the PROFIBUS.
Bus State:
“BusState" LED PROFIBUS DP interface state

Flashes red/green Interface module is waiting for PRO FIBUS parameter data
Lights up red Error on the PROFIBUS
Flashes green Interface module is waiting for configuration data
ID High and ID Low rotary coding switches
You can set the PROFIBUS address with the two ID High and ID Low rotary switches. The digits
selected via the two rotary switches together form the P ROFIBUS address in hexadecimal
format.
Example: To set the address 19 (= 13h), set the ID High rotary switch to position "1" and the ID
Low rotary switch to position "3."
