SIMATIC 505 PROFIBUS-FMS CP User Manual

Below

the LEDs is a recessed RUN/STOP toggle switch. The switch can be

moved from one position to another using a small tool, such as a

screwdriver

. The switch is recessed to prevent accidental switching of the

module from one state to another

The RESET button is recessed to prevent accidental reset of the module.

When the RESET button is pushed, the module resets as if power were

turned off and then turned on. Therefore, if the RUN/STOP switch is in the

RUN position and the module is functioning properly

, the module begins to

transmit and receive communications after going through a normal

power

-on start-up sequence.

WARNING

The

RESET button is for the unusual circumstance in which there is a module

function error that cannot be fixed with the COM5434 Configurator software.

When the RESET button is pushed, the module enters the state of global reset,

which is the same as a power-up. The hardware is reset, all communication is

terminated on all ports, and the LEDs turn off.

Because all communication that is controlled by the module is terminated,

essential messages to other nodes that control I/O functions can be disrupted.

Disrupting communication during plant operation could result in damage to

equipment and/or injury or death to personnel.

o avoid possible damage to equipment and/or injury or death to personnel, do

not reset the module without first understanding all possible results based on

the setup of your network.

The

RS-232 port is a 9-pin male D-shell connector

. Y

ou can set the RS-232

port to 9600 baud, 19200 baud, or 38400 baud using a jumper on the board.

The baud rate of the port must be set before the FMS CP module is installed

in the base. See Section 2.2 for instructions on how to set the baud rate of

the port.

The RS-485 PROFIBUS-FMS port is a 9-pin female D-shell connector

. Y

set the baud rate for the PROFIBUS port during network configuration

using the COM5434 Configurator

, as decribed in Section 5.4.
