SIMATIC TI505/TI500 MODNIM User Manual
The
block of 10 dipswitches is used to configure the network communication
parameters, which include data transmission rate, stopbit selection, parity
,
transmission mode, RTS/CTS handshaking, and output coil mapping.
(NOTE:
For all Series 500 MODNIM dipswitch settings, see Figure 1-6.)
Switches 1 through 4 are used to set the data transmission rate. All devices
on the network must be configured to communicate at the same data rate.
Switch settings for each of the available data rates are shown in Figure 1-4.

Switch 5 is used to select 1 or 2 stopbits. Set switch to the left for 1 stopbit,
to the right for 2 stopbits (on Series 505; for Series 500, see Figure 1-6).
Switch 6 is used to select Parity or No Parity when communicating over an
RS-232-C data link. T
o select Parity
, set switch to the left, then determine
whether you need odd or even parity and set switch 7 accordingly
.
If you selected Parity with switch 6, then you must also select either Odd or
Even Parity using switch 7. This switch is active only if switch 6 is set to
Parity
. Set switch to the left for Even parity
, to the right for Odd parity
.
Switch 8 is used to select ASCII or RTU mode of transmission. Slide switch
to the left for ASCII mode, to the right for RTU mode.
Switch 9 is used to enable or disable RTS/CTS handshaking. If you are
using point-to-point connections without using modems, you can disable
RTS/CTS handshaking by setting switch 9 to the left. Set switch 9 to the
right to select RTS/CTS handshaking for use with modems.
Switch 10 is used to determine whether the MODNIM collects data from the
PLC’
s Discrete Output (Y) memory or the Control Relay (C) memory
. Set
switch to the left for C coils, to the right for Y outputs.
