[438]ZEN Communication Protocol

1. Communication Processing
1.1. Send/Receive Processing
Send and Receive are completed by interrupt processing and the actual commands are processed by peripheral service processing.
In the peripheral service, there seems to be no processing to take time such as the processing over more than one scan; thus, time slice
processing is not executed. (The processing that needs writing to EEPROM is assumed to take time; however, SLC has restrictions on its
status (screen) that makes write-processing possible, and the data size written to EEPROM is not so big. Thus, it is considered as no
problem.)
1.2. Connection Recognition
Connection recognition is executed in peripheral service processing every scan.
P92 and 93 are checked and if a tool cable exists, communication processing is initialized to make communication possible.
If the status changes to no connection on the contrary, communication processing is also initialized.

4.2. Caution when adding commands
When new commands are added, it is necessary to note the following points:
・
As explained in the section 4.1, Exclusive Access Control is executed to each command per SLC screen. It is decided by Screen-to-software
command Process Disabled Flag. When new commands are added, the Screen-to-software command Process Disabled Flag (Software
Command Process Disabled Flag Table) needs to be added as well. Each command processing should be decided whether executable or not
per screen state according to this flag.
In addition, the Screen-to-software command Process Disabled Flag is provided for only 32 bits (32 commands), so commands should be
added wihtin this range (if this range is going to be exceeded, the area expansion of the flag needs to be studied).
This flag range
corresponds to command numbers, and the command numbers should be from 0 through 31.
・
If a screen is added, it needs to be added in the shaded part of the section 4.1 as well. Each command is studied whether executalbe or not
on the added screen.

■ Processing Overview
・
・
・
・
・
Writes data of a specified size from a specified IOM relative address.
Writes data to all relay areas.
Writes data to System Setup Area too.
Enables data to be written at a time if written to IOM Area and System Setup Area respectively.
Enables a bit to be specified (one bit for one command only).
■ Command Description
<IOM Relative Address>
Accessed in increments of word.
See 3.1.IOM Area Image and 3.2 System Setup Area for the IOM relative address of each area.
<Write Data Size>
Specified in Data Area Length.
Normal End without any processing when the data size is 0.
With IOM specified, if bigger than 34 Normal End after writing data of 34 bytes.
With System Setup Area specified, if bigger than 71 Normal End after writing data of 71 bytes.
<Write Data>
Writing data of an area less than one byte is written as it is without masking its non-existing bit areas.
Each IOM area has 2 bytes, so in the case of continuous writing over areas or writing at a time, data is written to non-existing relay
numbers as well.
<System Setup Area>
If data is written to System Setup Area, the range of the set values is checked. If the data is incorrect, it is regarded as Set Value
Error and no data is written.
<Password Check>
Executed when System Setup Area is accessed.
If any one of places is applied to Password Check, nothing is set and it is regarded as a password error.
<Password>
Password Area is not specifiable. Use UM Protect Command if you want to access it.
■ Response
<End Code>
$00: Normal End
$02: Address Over (when a specified address exceeded an IOM relative address or the address overflowed because of the Write data
size)
$03: Sum Value Error
$04: Set Value Error (when data was written to the System Setup Area but the set value was out of range.)
$06: Password Error (during password setting)
$0A: LCD Exclusion Error
■ Remark
・
・
・
No data is written to Button Input Area.
In writing to System Setup Area, data is transferred to EEPROM Area and the sum value is regenerated.
Reflection Timing of System Setup Area, Processing
Daylight Saving: Reflected in the common processing. Without RTC, Normal End after nothing is written.
Language Setting: Directly written to the applicable work.
Backlight: Directly written to the applicable System Setup Area. It is reflected at the time of a key entry and display instruction.
Without LCD, Normal End after nothing is written.
Contrast: Calls contrast processing. Without LCD, Normal End after nothing is written.
Input Filter: Directly written to the applicable System Setup Area. However, it is after RUN initial processing that the data is
reflected as a set value.
Modem Initialization Command: Directly written to the applicable System Setup Area.
Modem Send Delay: Directly written to the applicable System Setup Area.
Node No.: Directly written to the applicable System Setup Area. Reflected from next scan. Without match of the setting with the
software tool, communication is disabled.
Note: The end of Modem Initialization Command is decided by $20. $20 is set in the end in the software tool.

■ Command Description
<IOM Relative Address>
Accessed in increments of word.
See 3.1.IOM Area Image and 3.2 System Setup Area for the IOM relative address of each area.
<Read Data Size>
Normal End without any processing when the data size is 0.
With IOM specified, if bigger than 34 Normal End after reading data of 34 bytes.
With System Setup Area specified, if bigger than 71 Normal End after reading data of 71 bytes.
<Read Data>
Read data of an area less than one byte is read out as it is without masking its non-existing bit areas.
Each IOM area has 2 bytes, so in the case of continuous reading over areas or reading at a time, non-existing relay numbers are read
out as well. No guarantee for the read data size.

Releases errors in a SLC.
■ Command Description
・
・
・
Releases all errors.
Normal End without errors.
After Fatal Error occurs in RUN, releasing the error without changing the mode turns the mode to STOP (to detect errors again in
RUN initialization and so on).
■ Response
<End Code>
$00: Normal End
$03: Sum Value Error
■ Remark
・
・
・
Releases an error code within command processing. If cannot be released, the error has a release-impossible flag, and the
command does not release the flag. It is output again by common processing.
Also the display of the SLC is restored from an error screen.
Calls error release and screen restore.

■ Processing Overview
・
・
Reads out the present value of an instruction (T, C, A, Hold Timer) having a present value. And returns the status for an instruction
(T, C, D, Hold Timer) having a status (See “Command Data Area: with 1 parameter specified).
Able to read out the present values of two relay numbers in one instruction if the instruction is T, C, or Hold Timer (P instruction)
(See “Command Data Area: with 2 parameters specified).
■ Command Description
<Code per Instruction Type>
$00: Analog Input Value
$01: Timer
$02: Hold Timer
$05: Counter
$06: Analog Comparator
$07: Display
Reads the present value of only Timer, Hold Timer and Counter when 2 parameters are specified.
Normal End without any processing if no applicable instruction code exists or Busy Flag is not turned on.
Does not check the Busy Flag if 2 parameters are specified. Returns the present value stored at that point.
Returns the voltage conversion values (BCD) of $00: Analog Input 0 (I4(Ia)) and $01: Analog Input 1 (I5(Ib)) by setting $00/$01 to relay
numbers when analog input value ($00) is specified.
■ Response
<End Code>
$00: Normal End
$03: Sum Value Error
$0A: LCD Exclusion Error
<Present Value>
・ In the case of Timer, Hold Timer and Counter, returns a 2-byte present value and status.
・ In the case of Analog Comparator, returns a 4-byte conversion value in the order of analog input 1/2.
・ With 2 parameters specified, returns an applicable 2-byte present value.
・ In the case of Display, the present value does not exist and status is moved up to the front and set.
・ When Analog Input Value ($00) is specified, returns a 2-byte voltage conversion value of Analog Input 0(I4(Ia)) or Analog Input
1(I5(Ib)).
<Status>
・ Returns a 1-byte status for Timer, Hold Timer, Counter, and Display.
・ Analog Input Value and Analog Comparator have no status area.
・ Does not return a status when 2 parameters are specified.
Status Bit (common in all instructions)
D6: Trigger input status
D5: Reset input status
D4: Direction input status
Indefinite for the other bits
■ Remark
・ The present values of Weekly Timer and Calendar Timer are read out by the Clock Read command.
