1 6 LED Indicators
RMS1-GR device has 3 LED Indicators: Power, Rx and Tx
Power LED
This LED indicates different device statuses.
When energizing the equipment, the Power LED flickers rapidly during the first 7 seconds,
indicating the time to enter the “ FG” command that gives you access to the configuration of
the device. If you have not entered the command within this time, the Power LED remains
ON during the rest of the operation, indicating that the equipment is energized.
In case the command FG is entered, the Power LED flickers slower while remaining in the
configuration mode. When you exit this mode, the LED remains permanently ON.
Tx and Rx LED’s
The Rx LED flickers when it receives a Modbus packet from the master, even if this packet is
not for the slave ID that is receiving it.
The Tx LED flickers when a valid Modbus packet is sent to the master. When exceptions are
sent it does not flicker.

3Serial Configuration
3 1 General Description
The RMS1-GR equipment features a configuration mode through a very intuitive Serial
console that allows quick and simple configuration of the equipment.
You gain access to the configuration menu within 7 seconds after powering up the
equipment. It starts with a serial port configuration of 9600, 8, N, 1 and you gain access to
the menu by entering “ FG” (not case sensitive). The equipment will remain in the
configuration menu until a restart or the selection of the exit option in such menu. After this
step, the equipment is ready to accept queries from any Modbus master.
The menu has numerical options, that is, the user can only enter numbers to select different
configurations. By pressing the ES key you go backwards in the menu, undoing the
previously entered option.
3 2 Screens and Configuration Menus
Soon after FG is entered you gain access to the main menu:

4Modbus Map
4 1 Description of the Modbus Map
The Modbus Map is shown below with the memory zones corresponding to each one of the
registers of the Modbus Slave.
The RMS1-GR has 16 digital inputs, 16 digital outputs and 6 analog inputs.
It should be noted that address 30009 of the INPUT REGISTER, which contains the digital
input statuses of the equipment, bit 0 (or the least significant) corresponds to digital input 1,
and bit 15 (the most significant) corresponds with digital input 16.
The same thing happens with address 30011 of the INPUT REGISTER, which contains in this
case, the status of digital outputs, bit 0 (or the least significant) corresponds to digital output
1, and bit 15 (or most significant) corresponds with digital output 16.
The INPUT STATUS register of address 10001 to 10016 contains in each one of its addresses
the individual status of each one of the digital inputs.
The OIL STATUS register 00001 to 00016 contains in each one of its addresses the
individual status of each one of the digital inputs.

Register 1 up 10 and Register 12 are general pu

Register 11 is for Digital Output write.

RMS1 – GR User’s Manual Exemys
www.exemys.com 15
The HOLDING REGISTER 40001 to 40010 and 40012 are used for general purpose only. This
means that you can save data for later use. The register 40011 is used to write all the Digital
Outputs at the same time. If you write any Digital Output the register’s value will change too.
Ex.
If you write ‘2’ in the 40011 register.
40011: <00002> 00001: <0>
00002: <1>
00003: <0>
00004: <0>
00005: <0>
00006: <0>
00007: <0>
00008: <0>
00009: <0>
00010: <0>
00011: <0>
00012: <0>
00013: <0>
00014: <0>
00015: <0>
00016: <0>
Now it will change OIL 00001 register’s value, writing to it ‘1’. The 40011 register’s value
will change to ‘0003’.
00001: <1> 40011: <00003>
00002: <1>
00003: <0>
00004: <0>
00005: <0>
00006: <0>
00007: <0>
00008: <0>
00009: <0>
00010: <0>
00011: <0>
00012: <0>
00013: <0>
00014: <0>
00015: <0>
00016: <0>
If you write a value bigger than the equipment can handle (if it has 16 Digital Outputs you
can write a value less than 65535) it only will write the less significant value.
Ex.
If the equipment has 8 Digital Outputs and you write ‘65000’ the value that will be
written is ‘232’ because the last 8 bits of the value count.

-Same ser al port conf gurat on (baud rate, par ty, Modbus type)
-Same Modbus ID
On the master module you can also set the message t me out and t me between polls. Typ cally you won’t have to
