Low order communications (read) (option)
16.1 Outline
*When use low order communications, set communication type to [High + low order (read)] (Refer to 13.11.5).
Low order communications are functions that this recorder works as a master unit (high order
instrument) communications and reading data of the other instruments which are connected as slave
units (low order instruments) assigned for input channel of this recorder and then displaying and
recording the data. This recorder and low order instruments communicate by serial communication of
RS-485 communication standard compliance.
The “range”, “scale”, “RJ”, and “burn out” settings can be set for lower order instrument.*1
Data requirement for each instrument is approximately 1 second (all points per 1 instrument). When
connect 5 instruments to low order side, data renewal period is approximately 5 seconds.*3
*1 LT230, LT350/370, LT830, JU, JW has only data collective
function, not setting.
*2 Data renewal time is different depending on regulated points
only JW.
Less than 10 points: number of connection lower-order
communication instrument x 1 (second)
10-13 points: number of connection lower-order communication
instrument x 2 (seconds)
More than 13 points: number of connection lower-order
communication instrument x 3 (seconds)

Need the communication unit etc. that is corresponded
communication control procedure model 4.
Following devices can be inputted
.
・
D0000 to D1023
・
M0000 to M2047
*5 Data of following PLC made of Omron can be read.
・
The instrument which is corresponded SYSMAC C mode command communication.
Following channels can be inputted.
・
Data memory (DM) area
:
D0000 to D9999
・
CIO (input and output relay etc.) area
:
0 to 6143
When communicate with PLC of Omron, need line convertors (SC8-10) same as the number of PLC
(refer to 5-7(5)).

Data renewal period: approximately 1 second per 1 instrument.*
* Display of renewal may delay in this instrument depending on the condition of data renewal or
communication response delay of low order side instrument.
•
Communication time out: approximately 1 second for each instrument (no retry). Retain the data of
last value.*
*When communication time out is occur for the 60th times in a row, display and record “UNDER”.
