6.13 MODBUS TCP
The fieldbus Modbus TCP comes as a standard feature on the Ethernet port in the Expert controller. This is a
Modbus variant used for communications over TCP/IP networks, connecting over virtual port 502. By default the
Modbus TCP fieldbus does not have any I/O assigned. See section "3.3.5 I/O Tab" on page 78 to learn how to
edit the I/O. See section "6.12 Assignable Input and Output Functions" on page 126 to learn about the values
to edit. There is no configuration or programming specifically for the Modbus protocol itself. The Alpha's CPU

Asserts at the end of a fastening cycle when the achieved torque value is below the Low Torque limits Audit
step. Resets when the tool is commanded to start again. Can also be reset with the RESET RESULTS STATUS
input.
Size: 1 bit
Configuration:
Contact Type: Normally Open (N.O.), Normally Closed (N.C.)
Step: Audit, Audit-1, Audut-2
Output Type: Normal, Timed, Flash
Minimum ON Time, Time, Period
Spindle: Type the spindle number from which the signal come
Asserts at the end of a fastening cycle when the achieved torque value is within limits for the Audit step. Resets
when the tool is commanded to start again. Can also be reset with the RESET RESULTS STATUS input.
Size: 1 bit
Configuration:
Contact Type: Normally Open (N.O.), Normally Closed (N.C.)
Step: Audit, Audit-1, Audut-2
Output Type: Normal, Timed, Flash
Minimum ON Time, Time, Period
Spindle: Type the spindle number from which the signal comes.
This output will be one of three selections. The selections are the User Defined Value for the associated torque
status of the last fastening cycle. For example: if the last fastening cycle's torque status was High, and the User
Defined Value for High is +, then this output value is +.
The OK User Defined Value is selected when the achieved torque for the defined step are within specified limits.
The Low User Defined Value is selected cycle when the achieved torque for the defined Step is below the Low
Torque limit.
The High User Defined Value is selected when the achieved torque for the defined step is above the High Torque
limit.
It asserts when the fastening cycle is complete (before the IN CYCLE bit resets). The value resets to zero (0)
when the tool is commanded to run again.
Size: Can be any size from 0 to 32 bytes depending on Data Type
Configuration:
Data Type: Float, Int8, Int16, Int32, Fixed Point, String
OK: User Defined Value
Low: User Defined Value
High: User Defined Value
Step: Audit, Audit-1, Audit-2
Spindle: Type the spindle number from which the signal comes.
