Getting Started
Building the RSTi
Step 1: Open the individual boxes and remove modules.
Step 2: Attaching the MODBUS TCP/IP network adapter to the DIN rail:
Remove the end cover from the right side of the MODBUS TCP/IP Network Interface module (Part
Number STXMBE001) by sliding the end cover up. On the bottom of the network adapter release the
DIN rail locking mechanism by flipping the blue lever downward. Place the network interface module
on the DIN rail and engage the DIN rail locking mechanism by flipping the blue lever back to the
original position. The module should now be firmly secure on the DIN rail.
Step 3: Attaching the first I/O module:
Open the DIN rail locking mechanism on the bottom of the ST-1218 I/O module by flipping the blue
lever downward. Slide the I/O module onto the network interface module, from top to bottom, until it
is securely on the DIN rail. Lock the I/O module onto the DIN rail by engage the DIN rail locking
mechanism. (Flip the blue lever back to the original position).
Note: The RSTi does not limit the sequence of the I/O modules. For the purpose of the startup guide we will
place the modules in the following sequence.
1. MODBUS TCP/IP Network adapter (STXMBE001)
2. 24VDC discrete input module (ST-1218)
3. Analog input module (ST-3214)
4. Analog output module (ST-4212)
5. 24VDC discrete output module (ST-2328)
6. End cap cover
Step 4: Attach the remaining modules following the sequence in Step 3. Once all modules are securely
attached to the DIN rail place the end cap cover on the right most module.

Step 5: Attaching 24VDC Power to the Network
Interface:
Connect + 24VDC from the power supply to
the terminal 0 of the MODBUS TCP/IP
Network Interface Module by pushing in on
the spring clamp release button (Red).
Attach 0VDC power from the power supply
to the terminal 1 of the MODBUS TCP/IP
Network Interface Module by pushing in on
the spring clamp release button (Black)
Note: The 24VDC power is used to power up the
network interface module. Internally the
24VDC is converted to 5VDC that is used for
the network interface module and is also
transferred to all the I/O modules attached
to the network interface. If field devices like motors and switches are going to be wired to the RSTi
Starter Kit a separate 24VDC power supply is required and should be connected +24VDC to terminal 6
and 0VDC to terminal 4. Attach terminal 2 to earth ground.
Step 6: Apply power to the RSTi and connect the Ethernet cable from the PC to the RSTi Modbus TCP/IP.
The following LEDs should be observed on the RSTi Network Interface and I/O modules.
MODBUS TCP/IP Network adapter (STXMBE001)
Mod LED – Steady Green ON
LINK LED – Green ON (If LED is off check cable connections to the PC)
ACTIVE LED – OFF (LED will be off until the PC sends activity to the RSTi)
I/O LED – Green ON indicating that I/O bus is working properly. If off check to make sure the
modules are seated properly.
Field Power LED – OFF if no power is applied to pins 4 or 5 (Ground) and pins 6 or 7 (+24VDC)
24VDC discrete input module (ST-1218)
Status LED – Green ON for normal operation.
Input LEDs – OFF unless an input has been connected and in the ON state.
Analog input module (ST-3214)
Status LED – Green ON for normal operation.
Input LEDs – Solid Red ON. No inputs wired to inputs, this is a normal operation. Diagnostics is
detecting no load or open channel.
Analog output module (ST-4212)
Status LED – Green ON for normal operation.
Output LEDs – Solid Green ON. Normal operation.
24VDC discrete output module (ST-2328)
Status LED – Green ON for normal operation.
Output LEDs – OFF. Normal operation.

System Modules Specifications
Note: The Bus Master (ST-5725) and Slave (ST-5726) enables the RSTi to break the bus in the event that panel
width or the user wishes to distribute the modules. When expansion is required, add a Bus Master to the end
of the DIN rail section, then put in a Bus Slave at the beginning of the next set of I/O modules. Connection
between the master and slave is a twisted shielded cable. The master and slave have screw terminals so you
don’t need special connectors. The Master-Slave network is NOT multi-drop. Each Master can have only 1
Slave. You can add more drops by putting a Master at the end of the second DIN rail and connecting to
another Slave. The limit is 3 Master Slave pairs with a total distance of 300 meters. The maximum number of
modules allowed is a total of 32, Master and Slave modules occupy a module address.
