Overview

The TS-1700 is a modbus peripheral device which brings out 8 DIO, or 8 one wire temperature sensors.

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.

Holding Registers

The holding registers include various settings such as the configurable Modbus Address, termination enable, and more. These settings are common to all of our Modbus peripherals, and are stored in flash to persist between power cycles.

The Modbus protocol supports 64K

Address	Access	Description	Example Values
0x70	Read/Write	Modbus Mode	0 = ASCII, 1 = RTU
0x71	Read/Write	RS485 Bus Termination Enable	0 = No termination, 1 = enable termination
0x72	Read/Write	Modbus Device Address	0-65535
0x73	Read/Write	Modbus baud rate
0x74	Read Only	Unit Model	TS-1700
0x75	Read Only	Verilog Version	1
0x76	Read Only	ZPU Version	1
0x77	Read Only	Power Supply in millivolts	24000
0x78	Read Only	Internal Temperature in 1/100th degree Celsius	22000
0x79	Read Only	Reserved	N/A
0x7a	Read Only	Reserved	N/A
0x7b	Read Only	Reserved	N/A
0x7c	Read Only	Reserved	N/A
0x7d	Read/Write	Write value 0xfeed to make holding registers persistent	N/A

Connectors

2x RJ45

Both RJ45 ports, and all of our Modbus based devices are designed to be compatible with 2W-MODBUS RJ45 following this pinout:

16 Pin Terminal Block

The terminal block is a removable connector that includes 5V digital I/O. Every '+' pin is configurable using the Modbus registers, and each pin labelled '-' is connected to ground.

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:
