Page 9: Push Button
NOTE To configure the device, it must be connected to power at 10/30 V DC. c. Push button The push button located on the front panel of the housing can be used to initiate a Modbus/Radio cycle. This lets you test the Modbus configuration and radio connectivity. -
Page 10: Normal Start-Up Behavior
Normal start-up behavior GREEN When the device is switched on, after a brief delay, the light flashes rapidly for about ½ second to indicate that the device has started up correctly. The periodic frame is then sent out, based on the statement period specified GREEN in the settings. - Page 11 Frame period A complete radio cycle is composed of two phases: 1/ sending requests to one or several Modbus slave(s), 2/ broadcasting retrieved Modbus data via radio communication. During requesting phase, up to 49 Modbus request frames are sent through serial link to slave Modbus equipment, which return data requested by the ACW-DINRSM.
- Page 12 Therefore, you must configure the following parameters: Modbus function code The following function codes are available: Function code Name 0x01 Read Coils 0x02 Read Discrete Inputs 0x03 Read Holding Registers 0x04 Read Input Registers Concatenation with previous frame This parameter provides the option to not create a new radio frame and to include the result of the Modbus frame with the result of the previous Modbus/radio frame.

Page 13: Configuration Via Usb
b. Configuration via USB For a DINRSM with application software version Use ACW configuration tool version V3.0 or earlier V3.7.15 or later V3.2 or later V4.4.0 or later V3.3.5 or later V4.5.9 or later Download and install the configuration tool “setupACW.exe” at: https://www.atim.com/wp-content/uploads/documentation/CONFIGURATEUR/ACW/configurateur-acw.exe Connect the ACW-DINRSM to your computer with a micro-USB cable, then start the ACW configuration tool. - Page 14 Four major sections can be distinguished here. The ‘Serial parameters’ section is at the top left, “Other parameters” at the center left, the Modbus configuration section at the right and the debugging area at the bottom. Parameter settings for Radio and Modbus frames In the Modbus section at the right, you can add radio (network) and Modbus frames, add a Modbus frame to a radio (network) frame, edit a Modbus frame as well as delete and test Modbus frames.
- Page 15 Testing Modbus frames Before testing a Modbus frame, you must connect the ACW-RSM to your Modbus slave device. Next, configure the parameters for the serial link and click ‘Apply’ to apply the serial parameters. Create a Modbus frame by pressing ‘A’, clicking the ‘Add’ button or by right-clicking and selecting from the context menu.
- Page 16 Configuration example In this example, we have 3 radio frames with headers of 40, 41 and 90 plus 7 Modbus frames. Radio frame 40 contains 4 Modbus frames; radio frame 41 contains 2 Modbus frames; and radio frame 90 contains just one Modbus frame. The figure below shows the radio frames that will be sent out (if the Modbus slaves respond): Radio frame 40 Byte...

Page 20: Receiving Information From Iot Networks (Sigfox/Lorawan)
Receiving information from IoT networks (Sigfox/LoRaWAN) You can use this feature if your product includes a compatible radio version. • Sigfox radio firmware: Version 5931 or later • LoRaWAN radio firmware: Version 2.3.3 or later The document ATIM_ACW-DLConfig_UG_EN.pdf explains how exchange frames work for this function. NOTE IMPORTANTE When you send the command to request the ACW configuration, several uplink frames will be sent. - Page 21 • 0x50 = 38400 bps • 0x60 = 57600 bps • 0x70 = 115200 bps Serial link parity – Byte 3 – bits 0 to 1 The possible values in byte 3 for these bits are: • 0x00: No parity. (default) •...

The default configuration and minimum value is 10 minutes (0x000a). The maximum value is 40320 minutes, i.e. 4 weeks. Modbus frame parameters (Code 30 to 61) These parameters are ‘buffered’...
- Page 23 Concatenation – Byte 1 – bit 7 This parameter is masked with the function code parameter to concatenate multiple registers from multiple Modbus frames in a single radio frame. The possible values in byte 1 for these bits are: • 0x00 = No concatenation or creates a new radio frame.
