Overview
The TS-1700 is a Modbus peripheral device that provides a combination of up to 8 connections, consisting of a mix of DIO and 1-wire temperature sensors.
Getting Started
Power Requirements
The TS-1700 will operate within a range of 10-28 VDC on either Modbus port. Power supplied on the Modbus port is passed along the bus as an active power rail on the other Modbus port. Do not apply power to both Modbus ports.
Features
TS Modbus Support
When using all Technologic Systems Modbus devices we include functionality to create an arbitrary chain of stock peripherals to automatically enumerate all connected devices, configure them them, and generate an I/O map of all connected devices.
TS Modbus Autoconfiguration
The autoconfiguration works by using the optional mode pin on the RJ45 connector as designated in the MODBUS-2W standard. Technologic Systems uses this to indicate if it is a TS device. If it is asserted (low) to a TS device, then it will allow access to the #Holding Registers at address 0xfe. Normally 0xfe is not a valid address in Modbus, so this will not interfere with other devices.
This will identify the TS Modbus device model and revision, set the first device in the chain to 0x80, and then asserts the mode line to the next port to enumerate the next device. The next device address is set to 0x81, and they continue to increment 1 until no slave responds to the mode line indicating that all salve devices have been discovered. At this point the last device in the chain is configured to enable termination on the RS485 link, and all devices have their speed bumped up to 1M baud.
One-Wire Temperature Sensors
The TS-1700 supports any temperature sensor using the Maxim DS18B20 IC.
| Temperature Range | -55C to 125C |
|---|---|
| Resolution | 0.0625 degrees |
| Update Rate | 750ms |
| Accuracy | Maximum error 0.5 degree from -10C to 85C. The maximum is 2 degrees for the full -55C to 125C. |
| Maximum Sensor Cable Length | Greater than 350 feet |
Register Interface
Holding Registers
The interface to all Modbus peripheral devices consists of a set of 127 holding registers. These registers are used to configure the device operation, read and write input output parameters, as well as various settings used to configurable Modbus Address, Termination enable, Data Format, and Bit Rate. These settings are common to all of our Modbus peripherals and can be persisted in on-board flash memory.
NOTE: The device operates ONLY in Modbus RTU communications mode. Modbus ASCII is not presently supported.
Common Configuration Holding Registers
| Address (hex) | Address (dec) | Access | Description | Example Values |
|---|---|---|---|---|
| 0x70 | 112 | Read/Write | Modbus Mode | 0 = ASCII, 1 = RTU |
| 0x71 | 113 | Read/Write | RS485 Bus Termination Enable | 0 = No termination, 1 = enable termination |
| 0x72 | 114 | Read/Write | Modbus Device Address | 1-246 (0x01-0xf7) |
| 0x73 | 115 | Read/Write | Communication Bit Rate | Communication Bit Rate |
| 0x74 | 116 | Read Only | Unit Model | TS-1700 |
| 0x75 | 117 | Read Only | Verilog Version | 1 |
| 0x76 | 118 | Read Only | ZPU Version | 1 |
| 0x77 | 119 | Read Only | Power Supply in millivolts | 24000 |
| 0x78 | 120 | Read Only | Internal Temperature in 1/100th degree Celsius | 22000 |
| 0x79 | 121 | Read/Write | Reserved | N/A |
| 0x7a | 122 | Read/Write | Reserved | N/A |
| 0x7b | 123 | Read Only | Reserved | N/A |
| 0x7c | 124 | Read Only | Reserved | N/A |
| 0x7d | 125 | Read/Write | Write value to pogrom configuration:
Set to 0xfeed to write configuration parameters to firmware. Set to 0xdead for full reset to default configuration (erases firmware settings). Set to 0xc0de for temporary configuration (resets to firmware saved settings on power cycle). In all cases the value is set to zero when completed. |
0xFEED = Write configuration to storage, 0xDEAD = Erase configuration storage, 0xC0DE apply configuration but don't write to storage. |

- ↑ 1.0 1.1 1.2 1.3 1.4 1.5 1.6 1.7 The temperature is read in 1/100th degrees Celsius. The temperature is only readable when the sensor is connected and the DIO port is configured to read from the sensor (0x7a).
- ↑ The input values are reflected in each bit for the DIO that are configured as inputs. DIO not configured as an input will be 0
- ↑ The bits in the return value will correspond with the pin configuration at 0x121 to show which pins are configured as outputs
- ↑ Bits 0-3 of the return value correspond with the 4x optional membrane buttons on the outside of the case. The return value is already debounced, and will indicate with a 1 if the button is pressed.

Product Notes
FCC Advisory
This equipment generates, uses, and can radiate radio frequency energy and if not installed and used properly (that is, in strict accordance with the manufacturer's instructions), may cause interference to radio and television reception. It has been type tested and found to comply with the limits for a Class A digital device in accordance with the specifications in Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference, in which case the owner will be required to correct the interference at his own expense.
If this equipment does cause interference, which can be determined by turning the unit on and off, the user is encouraged to try the following measures to correct the interference:
Reorient the receiving antenna. Relocate the unit with respect to the receiver. Plug the unit into a different outlet so that the unit and receiver are on different branch circuits. Ensure that mounting screws and connector attachment screws are tightly secured. Ensure that good quality, shielded, and grounded cables are used for all data communications. If necessary, the user should consult the dealer or an experienced radio/television technician for additional suggestions. The following booklets prepared by the Federal Communications Commission (FCC) may also prove helpful:
