NOTE: The RMA PLUS will not function properly without the SD card inserted. If necessary, you may upgrade the SD card to a larger capacity and / or class if the new card is high capacity (SDHC). Extended capacity micro SD cards (SDXC) are not supported by this device. - Page 38 Unsupported data types are blank. This may be observed in a log file if the RMA PLUS cannot read the data type of a member. This will be the case if the target device is not present or the bus hasnot acquired the member attributes.

Page 39: Ethernet
The RMA PLUS embeds a 3-Port 10/100 Managed Ethernet switch. Therefore, you do not need a switch or router to cre- ate a simple network of devices. You may connect your PC directly to the RMA PLUS on either port. The other port can connect to another device (HMI, PC, RMA PLUS, etc.). -
Page 40: Multicast Storm Protection
The RMA PLUS currently implements IPV4 static and DHCP addressing. Static addressing is the preferred method. If DHCP is selected and the device does not get an address from the server, the RMA PLUS will fail to the static IP address after a timeout period. -
Page 41: Modbus® Tcp Server
The RMA PLUS is a Modbus® TCP server and provides up to three (priority based) Modbus® TCP sessions. This ser- vice is enabled by default for all model numbers. It may be disabled by writing “No” to the Modbus® TCP Enable mem- ber. -

Page 49: Modbus® Rtu
This feature is only available if the model number is RMAP-2XXX-XXXX. The RMA PLUS model RMAP-2XXX-XXXX enables two Modbus® RTU channels on an adjacent RS-232 / RS-485 companion module. These channels may be independently configured as masters or slaves. Modbus® RTU does not proxy requests. -
Page 50: Testing Modbus® Rtu Communications
To perform test read / write operations on the data you may use the Modbus® RTU test program included on the MICRO SD drive (sd:\Software\Modbus® RTU). In the following example, the RMA PLUS’s Hardware ID (32-bit Integer) is returned for registers 0, 1. Registers 2 and 3 were not specified so they return 0s. -
Page 51: Non-Volatile Memory
Standard Bus and Intermodule Bus Addressing The RMA PLUS uses a proprietary RS-485 token-passing network of both masters and slaves. The RMA PLUS is a master on both channels. Standard Bus Instance 1 is low-speed standard bus and Standard Bus Instance 2 is inter- module bus. -
Page 52: Intermodule Bus
There may be up to 33 devices (zones) on bus 2, each with a unique physical address used by the bus. The logical address is what the user is presented. By default, the RMA PLUS occupies logical address 7 of segment 2. You must ensure that each device on this bus has a unique logical address within its segment. -
