Error problem hm2 7i96s 7i77 analogout scalemax not found ?

Hello everyone, I'm back, happy 2025 to all. Please, I need help to return to the retrofit process of a punching machine.
I have the hardware configuration 7i96s + 7i77 + 7i84d and THCAD2
I need to make the 7i77 board work to drive the Z axis with feedback from the THCAD2. To get a basic code example, I used linuxCNC's PNCConf to generate a basic code example.

The basic code generated was:

# ---PWM Generator signals/setup---

setp hm2_7i96s.0.7i77.0.0.analogout0-scalemax [JOINT_1]OUTPUT_SCALE
setp hm2_7i96s.0.7i77.0.0.analogout0-minlim [JOINT_1]OUTPUT_MIN_LIMIT
setp hm2_7i96s.0.7i77.0.0.analogout0-maxlim [JOINT_1]OUTPUT_MAX_LIMIT

net z-output => hm2_7i96s.0.7i77.0.0.analogout0
net z-pos-cmd <= joint.1.motor-pos-cmd
net z-enable <= joint.1.amp-enable-out

# ---Encoder feedback signals/setup---

setp hm2_7i96s.0.encoder.00.counter-mode 0
setp hm2_7i96s.0.encoder.00.filter 1
setp hm2_7i96s.0.encoder.00.index-invert 0
setp hm2_7i96s.0.encoder.00.index-mask 0
setp hm2_7i96s.0.encoder.00.index-mask-invert 0
setp hm2_7i96s.0.encoder.00.scale [JOINT_1]ENCODER_SCALE

net z-pos-fb <= hm2_7i96s.0.encoder.00.position
net z-vel-fb <= hm2_7i96s.0.encoder.00.velocity
net z-pos-fb => joint.1.motor-pos-fb
net z-index-enable joint.1.index-enable <=> hm2_7i96s.0.encoder.00.index-enable
net z-pos-rawcounts <= hm2_7i96s.0.encoder.00.rawcounts

# ---setup home / limit switch signals---

net z-home-sw => joint.1.home-sw-in
net z-neg-limit => joint.1.neg-lim-sw-in
net z-pos-limit => joint.1.pos-lim-sw-in

But when trying to apply this example the error appears:

hm2_7i96s.0.7i77.0.0.analogout0-scalemax not found

The board The 7i77 electronics have all the necessary voltages, all the yellow LEDs are on and the green one too.

I have already managed to control the output and input through the classicladder, but unfortunately I am not having success in controlling the Z axis.

The HAL configuration is

loadrt hm2_eth board_ip="10.10.10.10" config="num_encoders=8 num_pwmgens=1 num_stepgens=5 sserial_port_0=3000"

Note: the number 3 in sserial_port_0 was necessary to recognize the 7i84d

How do I solve the error problem: hm2_7i96s.0.7i77.0.0.analogout0-scalemax not found?

I appreciate any suggestions or basic examples for configuring the 7i77

Has the 7I96S been programmed with 7i96s_7i77d.bin firmware?

Yes, the 7i96s board has been updated, attached readhmid and bin files. 

 

Look, like you have the channel number wrong for the analog 7I77 section
(its channel 1 not 0)
 

This error appeared when I took the data generated by PNCConf to try to include part of it in the programming code of the machine that I am already developing. But while I was waiting for your answer, I had the idea of ​​creating a new file through the basic PNCConf and gradually including the code of the machine under development. In this code, it is accepting the "analogout scalemax". I will leave it attached in case anyone needs a basic initial code for 7i96s with 7i77. I will try this method. Thank you for your attention, Mr. PCW.

 

Note, you can get a better idea of sserial channel --> 7I77 assignments with:

mesaflash --device 7i96s --addr 10.10.10.10 --dbname3 7i77 --readhmid

Thanks for the suggestion of the command below:

mesaflash --device 7i96s --addr 10.10.10.10 --dbname3 7i77 --readhmid

It's a great option to debug any problems. But unfortunately in my case it wasn't allowed, the error below appeared:

lbp16_access.send_packet: Operation not permitted
Aborted

Do I have to assign a name or register it in the system so that readhmid works through the name? If so, do you have an example?

You cannot run that command when LinuxCNC is running
or when it exited on a major error, because linuxCNC
blocks access to the Ethernet port it is using when it is running.

LinuxCNC restores access when it exits normally
