Page 8: Response Measures And Times
CHANNEL SPEED: Allows you to set the channel sampling time TERMINAL CONFIGURATION: Allows you to choose the configuration of the measurement terminals according to the Z-8TC-SI or Z-8TC-SI-LAB model. INTERPRETATION OF FLOATING POINTS: Allows you to set whether the single precision (32 bit) Floating Point registers are to be interpreted with the most significant value on the high word or on the low word. -
Page 9: Usb Connection And Configuration Reset
User Manual Z-8TC-SI CHANNEL OFFSET Allows you to set the measurement offset value. USB CONNECTION AND CONFIGURATION RESET The front USB port allows a simple connection to configure the device via the configuration software. If it is necessary to restore the instrument factory configuration, use the configuration software. -
Page 10: Modbus Communication Protocol
User Manual Z-8TC-SI MODBUS COMMUNICATION PROTOCOL The supported communication protocol is: Modbus RTU Slave (from both the RS485 and USB ports) ▪ For more information on these protocols, see the website: http://www.modbus.org/specs.php. SUPPORTED MODBUS FUNCTION CODES The following Modbus functions are supported:... -
Page 11: Modbus Register Table
According to the Modbus standard the Holding Registers are addressable from 0 to 65535, there are 2 different conventions for numbering the addresses: "0-BASED" and "1-BASED". For greater clarity, Seneca shows its register tables in both conventions. ATTENTION! CAREFULLY READ THE DOCUMENTATION OF THE MODBUS MASTER DEVICE IN ORDER TO UNDERSTAND WHICH OF THE TWO CONVENTIONS THE MANUFACTURER HAS DECIDED TO USE NUMBERING OF MODBUS ADDRESSES WITH "0 -BASED"... -
Page 12: Numbering Of Modbus Addresses With "1 Based" Convention
User Manual Z-8TC-SI The numbering is: HOLDING REGISTER MODBUS MEANING ADDRESS (OFFSET) FIRST REGISTER SECOND REGISTER THIRD REGISTER FOURTH REGISTER FIFTH REGISTER Therefore, the first register is at address 0. In the following tables, this convention is indicated with “ADDRESS OFFSET”. -
Page 13: Bit Convention Within A Modbus Holding Register
User Manual Z-8TC-SI BIT CONVENTION WITHIN A MODBUS HOLDING REGISTER A Modbus Holding Register consists of 16 bits with the following convention: For instance, if the value of the register in decimal is 12300 the value 12300 in hexadecimal is:... - Page 14 User Manual Z-8TC-SI REPRESENTATION OF A 32-BIT VALUE IN TWO CONSECUTIVE MODBUS HOLDING REGISTERS The representation of a 32-bit value in the Modbus Holding Registers is made using 2 consecutive Holding Registers (a Holding Register is a 16-bit register). To obtain the 32-bit value it is therefore necessary to read two...
- Page 15 User Manual Z-8TC-SI Using the last representation the value 2.54 is represented at 32 bits as: 0x40228F5C Since we have 16-bit registers available, the value must be divided into MSW and LSW: 0x4022 (16418 decimal) are the 16 most significant bits (MSW) while 0x8F5C (36700 decimal) are the 16 least significant bits (LSW).
