Hakko Electronics V Series - Indirect Memory Designation; User Log Read for Yokogawas PLC

Appendix 1 PLC2Way App1-17
Indirect Memory Designation
It is possible to have access to the PLC2 memory using the indirect memory designation as a macro
command.
In this section, the indirect designation of the PLC2 memory is explained.
The internal user memory ($u) is used for the indirect memory designation.
Designating the indirect memory
• PLC2 memory
- Memory type
Depends on the PLC model.
Refer to “Available Memory” in “Chapter 2” to “Chapter 33” when setting.
- Port number
Set the port number of the PLC connected at the MJ port.
User Log Read for YOKOGAWA’s PLC
The user log set with YOKOGAWA’s PLC “FA-M3/FA-M3R” connected at the MJ port can be read
using the macro command TEMP_CTL.
Macro
[TEMP_CTL]
This macro command controls the operation set in the memory addresses starting from the one
specified for F0 for the number of words specified for F1.
Usable Devices
TEMP_CTL: Temperature controller/PLC2Way control function
TEMP_CTL F0 F1
Return data: Data stored from PLC2Way to V7 series
*2 Set “0” for CPU No. 1.
*3 The registration number is stored in special register Z105.
*4 If there is no user log in the “n + 2” memory or there is an error in communications, [−1] is stored.
