1Introduction
1.1 Overview
The following two functions are incorporated into the UM33A/S006.
• Modbus/RTU master function (read only)
• Modbus/RTU communication data monitor function
The Modbus/RTU master function allows the registers of Modbus slave devices on the same circuit
line to be read out. The Modbus/RTU communication data monitor function allows communication
between a Modbus master and slaves to be monitored and the response values of the slaves to be
displayed.
This instruction manual describes the difference between this TOKUCHU model and standard model.
Before reading this document, please read the instruction manual of standard model (document
number: IM 05P03D21-01EN)

Data Monitor Function
3.1 Modbus/RTU Master Function
This TOKUCHU product has a Modbus/RTU master function. The Modbus/RTU master function allows
the registers of slave devices on the same circuit line to be read out and displayed on the UM33A
screen.
From the master side, Modbus Coil, Discrete Inputs, Holding Resister, and Input Resister can be read
out. The supported Modbus/RTU function codes are 01 (Coil), 02 (Discrete Inputs), 03(Holding
Resister), and 04 (Input Resister). The maximum number of read commands and displays is eight.

3.2 Modbus/RTU Communication Data Monitor Function
This TOKUCHU product has a Modbus/RTU communication data monitor function. The Modbus/RTU
communication data monitor function allows the monitoring of register readout communication
between a Modbus/RTU master and slave devices on the same circuit line. This function allows
communication response values transmitted on the same circuit line to be displayed on the UM33A
screen without the UM33A sending communication commands.
Communication to Modbus Coil, Discrete Inputs, Holding Resister, and Input Resister can be
monitored. The supported Modbus/RTU function codes are 01 (Coil), 02 (Discrete Inputs),
03(Holding Resister), and 04 (Input Resister). The maximum number of read commands and displays
is eight.
For the continuous readout commands sent from the Modbus master side to the slave side, the first
setting parameter length of data (16 bits (1 register) for the Bit and 16 bit integer data types and 32
bits (2 registers) for the 32 bit integer and FLOAT data types) can be obtained.

3.7 L-H and H-L Register Arrangements When 32 bit LONG or
FLOAT Is Selected
For 32 bit integer and FLOAT types, L-H or H-L order can be selected. Set it according to the devices in use.

Figure 3.6.2 32 bit H-L register arrangement
3.8 Display Screen (Communication PV1 to Communication PV8)
The measured value of the specified register (MB.ST menu) is displayed. Communication PV number
is shown on the group display. Only when the acquired data type is 16 bit integer, hexadecimal
expression can be used by changing FRMT (MB.ST menu) to HEX.
When the acquired data type is FLOAT and the auto range function is in use, a unit prefix is displayed.
The unit prefix display can be switched between “T, G, M, k, etc.” and exponential type (E03, E00,
etc.). Table 3 shows the unit prefix display during auto range. If the value is smaller than ±p (pico)
range when auto range is in use, “0” is displayed.

The unit display shows the selected unit (VOLT, A, C, etc.).
The display can be shown or hidden with the communication ONOFF (MB.ST menu) value.
When the communication function ONOFF (MB.ST menu) values are all set to hidden, only the PV
input is displayed.
If the PV input is hidden, at least one of the ONOFF (MB.ST menu) value is ON.
3.9 Display Screen (PV Input)
The PV input is displayed.
The unit (VOLT, A, C, etc.) is displayed.
The display can be shown or hidden with display U.PV (KLOC menu) OFF/ON value.
When the communication function ONOFF (MB.ST menu) (1 to 8) values are all set to OFF, the PV
input cannot be hidden. When any of the communication function ONOFF (MB.ST menu) (1 to 8)
values is ON, the PV input can be hidden.

3.10 Auto/Manual Switching of the Operation Screen
When auto switching of the operation screen is used, the PV input value switches automatically
between communication PV1, communication PV2, . . . communication PV8 at the specified display
update interval (3S, 10S, 30S, 1M).
When manual switching of the operation screen is used, the PV input value is switched between
communication PV1, communication PV2, . . . communication PV8 every time the DISP key is
pressed.
You can switch between auto switching and manual switching using the Fn key. Switching is also
possible using parameters.
3.11 Display Screen for Communication Errors
When a communication error occurs, the PV display area of the communication PV1 to
communication PV8 measurement display operation screen blinks.
In addition, if a communication error occurs in any of the communication PVs (PV1 to PV8), the EV
lamp 8 lights.
When a communication error occurs, the previously acquired value is displayed.
Note: On the standard UM33A, the decimal point blinks when a communication error occurs. This
feature is not available on this TOKUCHU product.

3.12 Retransmission Output
Retransmission output can be produced using 4-20mA by selecting PV, communication PV1 to
communication PV8.
The high and low limits of the scale are as follows:
○When RTS=PV: RTL + 1 digit to 30000
-19999 to RTH-1digit
The decimal place is the same as that of the PV input.
(This is the same as the standard UM33A.)
○When RTS=C.PV: RTL + 1 digit to 99999
-19999 to RTH-1digit
The decimal place is the same as that of SDP in MB.NT.
The setting range is the same also for FLOAT.
If communication is disconnected, retransmission output produces the
previously saved value.
Note: The communication PV retransmission output continues produce the selected communication
PV even when the operation screen is changed.
Note: Note that if the span exceeds 49999, the resolution of the retransmission output will
decrease.
Note: If the auto range function is enabled when FLOAT is in use, do not use the
retransmission output function.
Note: The retransmission output will be under 4mA until the communication establishes
because the initial value of communication PV is set to -19999 at Power ON.

10
3.13 Alarms and Event Lamps
The number of alarms is different between PVs and communication PVs.
PV: 4 alarms
Communication PV: 2 alarms (can be set only for a single communication PV)
Event lamps EV1 to 4 are for PV alarms. EV5 and 6 are for communication PV alarms. EV8 is for
communication error indications. These indications are fixed. They cannot be changed.
Event lamps do not change their indications even when the operation screen is different.
The indications are fixed as follows:
Note: If the auto range function is enabled when FLOAT is in use, do not use the
communication PV alarms.
