4.2 Host Setting
to activate Fieldbus, the following settings are
required for the host.
IMPORTANT
Do not turn off the main power supply and
fieldbus power supply immediately after set-
ting. When the parameters are saved to the
EEPRoM, the redundant processing is executed
for the improvement of reliability. If the power
is turned off within 60 seconds after setting is
made, the modified parameters are not saved
and the settings may return to the original val-
ues.

V (ST) Slot-Time Set 4 or greater value.
V (MID) Minimum-Inter-PDU-
Delay
Set 4 or greater value.
V (MRD)
Maximum-Response-
Delay Set so that V (MRD) 3 V
(ST) is 12 or greater
V (FUN) First-Unpolled-Node Indicate the address next
to the address range used
by the host. Set 0x15 or
greater.

Rotamass addess is
factory set to 0xF6. Set
this address to be within
the range of BASIC device
in Figure 4.2.

4.3 Power-on of
rOTAMASS and Bus
turn on the power to the host, bus, and
RotaMaSS. If any segments do not light, or if a
current anomaly occurs, check the voltage of the
power supply for the RotaMaSS.
using the host device display function, check that
the RotaMaSS is in operation on the bus. un-
less otherwise specified, the following settings are
in effect when shipped from the factory.
PD tag: Ft1004
node address: 246 (hexadecimal F6)
Device ID: 594543000Dxxxxxxxx (xxxxxxxx = a
total of 8 alphanumeric characters)
If no RotaMaSS is detected, check the avail-
able address range. If the node address and
PD tag are not specified when ordering, default
value is factory set. If two or more RotaMaSS
are connected at a time with default value, only
one RotaMaSS will be detected from host
as RotaMaSS have the same initial address.
Connect the RotaMaSS one by one and set a
unique address for each.
4.4 Integration of dd
If the host supports DD (Device Description), the
DD of the RotaMaSS needs to be installed.
Check if host has the following directory under its
default DD directory.
594543000D
(594543 is the manufacturer number of
Yokogawa Electric Corporation, and 000D is
the RotaMaSS device number, respectively.)
If this directory is not found, the DD for the
RotaMaSS has not yet been installed. Create
this directory and copy the DD files (0m0n.ffo and
0m0n.sym to be supplied separately where m and
n are numerals) to it. If you do not have the DD
files for the RotaMaSS, you can download them
via Internet from
http://www.yokogawa.com/fld/FIELDBuS/fld-field-
bus-01en.htm
once the DD is installed in the directory, the
name and attribute of all parameters of the
RotaMaSS are displayed.
off-line configuration is possible using the capa-
bilities file.
