Conventions Used in the Menu Pages
To better understand the menu pages that follow
review the naming conventions used. When encoun-
tered throughout this document, the word "default"
implies as shipped from the factory. Each page (Op-
erations, Setup and Factory) and their associated
menus have identical headers defined below:
Note:
The communications protocols and associated ad-
dressing mentioned below and found in the menus are
available only when another module equipped with
the protocol is used in conjunction with the RME. The
RME module by itself has Watlow's Standard Bus
only.
Header Name Definition
Display
Visually displayed infor-
mation from the control.
Parameter Name
Describes the function of
the given parameter.
Range
Defines options available
for this prompt, i.e., min/
max values (numerical),
yes/no, etc... (further ex-
planation below).
Default
Values as delivered from
the factory.
Modbus Relative Ad-
dress
Identifies unique parame-
ters using either the Mod-
bus RTU or Modbus TCP
protocols.
CIP (Common Indus-
trial Protocol)
Identifies unique param-
eters using either the De-
viceNet or EtherNet/IP
protocol (further explana-
tion below).
Profibus Index
Identifies unique param-
eters using Profibus DP
protocol (further explana-
tion below).
Parameter ID
Identifies unique param-
eters used with other soft-
ware such as, LabVIEW.
Data Type R/W
uint = Unsigned 16 bit
integer
dint = Signed 32-bit,
long
string = ASCII (8 bits
per character)
float = IEEE 754 32-bit
RWES = Readable
Writable
EEPROM (saved)
User Set (saved)
Display
When the RME module is used in conjunction with
the RUI (optional equipment) visual information from
the control is displayed to the observer using a fairly
standard 7 segment display. Due to the use of this
technology, several characters displayed need some
interpretation, see the list below:
[1] = 1 [0] = 0 [i] = i [r] = r
[2] = 2 [a ] = A [j ] = J [s] = S
[3] = 3 [ h] = b [ h] = K [ t] = t
[4] = 4 [r] , [C] = c [ l] = L [U] = u
[5]
= 5
[d ]
= d
[ m ]
= M
[u]
= v
[6]
= 6
[ e]
= E
[n]
= n
[ w ]
= W
[7] = 7 [ f] = F [o] = o [y ] = y
[8] = 8 [g ] = g [ p] = P [2] = Z
[9] = 9 [ h] = h [q ] = q
Range
Within this column notice that on occasion there will
be numbers found within parenthesis. This number
represents the enumerated value for that particular
selection. Range selections can be made simply by
writing the enumerated value of choice using any of
the available communications protocols. As an ex-
ample, turn to the RME Setup Page and look at the
Alarm Menu and then the Alarm Type. To turn the
alarm off using Modbus simply write the value of 62
(off) to register 401469 and send that value to the
control.
Communication Protocols
All modules come with the standard offering of Wat-
low's Standard Bus protocol used primarily for inter-
module communications as well as for configuration
using EZ-ZONE Configurator software (free down-
load from Watlow's web site ( http://www.watlow.com ).
The RM Access (RMA) module and the RUI can serve
as a gateway and have options for several different
protocols listed below:
- Modbus RTU 232/485
- EtherNet/IP, Modbus TCP
- DeviceNet
- Profibus DP

the Keyword field.
